Actually, diabetes insipidus is a condition where your body can't concentrate urine properly. You end up drinking a lot because you're dumping so much water (I've had patients go through 10L a day!) but the primary problem is not addiction to water, it's the peeing too much. You have to take in massive amounts of fluid just to compensate and stay hydrated.\n\nWhen you pathologically drink too much water it's called polydipsia.

Because in the summer, we lose a lot of sweat yes? =] so, this sweat has to be replaced with water from the body, meaning why we drink more in the summer, BUT, in the winter, we hardly sweat, meaning a build up of water, and bingo, out it comes, its all homeostasis, blood and body temperatures =], Basically, the water in our body cant escape  through the sweat glands, well, cus its winter, meaning it just builds up and puts everything out of balance. So we pee more. In the summer we dont pee asmuch cus water is lost through sweat.

Alcohol raises your blood sugar, which makes you hungry.

you drink that much because your body is telling you to drink.  maybe you just get dehydrated easily.  regardless, you can never drink too much water.

Before you seek any advice on how to balance your electrolytes, you should get your electrolytes checked. Have your doctor run a chemistry profile first. Sometimes, drinking a lot of fluids is your body's way of telling you that you need more fluids. Sometimes, it's a sign of a serious problem, though this is rare so don't get freaked out. Get more informed, and see your physician.

It is because after eating the concentration of sugar in the blood increases which leads to ex-osmosis ie movement of water from the body cells to the blood where there is high concentration of solute. The movement of water from the cell results in the reduced metabolism which courses one to feel sleepy.

We do not completely know how the brain generates the sensation of thirst, but that is where it arises. In simplest terms, when the body needs water, sensors alert the brain, and some signals—one of which is a peptide called angiotensin II—cause the brain to produce the sensation of thirst and to tell the body to start taking in more water immediately. If just a tiny amount of angiotensin II is injected into the correct area of the brain, thirst and drinking result. In addition, saliva flow is inhibited in a thirsty person, making the mouth dry and amplifying the sensation of thirst.\n\nThirst is clearly related to the volumes of vascular space (in blood) and extravascular space (outside blood). When the body loses water, these spaces are less full. Sensors report that situation to the brain, and thirst results. This simple picture is made much more complex by the action of the kidneys, which either excrete or retain water, and a person's salt intake, which affects the concentration of salts in the vascular and extravascular spaces. If the body loses pure water and no change in salt content occurs, the concentration of salt rises, causing an imbalance in the body's biochemistry. Therefore, our physiological controls work to keep salt concentrations within normal limits. For example, the body retains or excretes water, or it responds to thirst by bringing in new water. The body also excretes regulated amounts of salt through the kidneys, in perspiration, in saliva, and in tears.\n\nWhen you exercise or work hard, you lose water through perspiration and transpiration (breathing). You may also lose some salt when you perspire. By the time most people feel thirst, they are already considerably dehydrated (too little water). The reason is that the vascular and extravascular spaces must actually shrink enough for the sensors to tell the brain to get more water. It is better to drink water before and during the exercise or work—before you feel thirsty—so that you do not become dehydrated. In addition, salt pills are almost never needed, even with heavy perspiration. If your salt level is low, your body will reduce the amount of salt contained in your sweat and you will not lose much.

drinking a lot of fluid??  Diabetes??

because if you feel deprived or denied of something (food in your case); you want to fill that void with something else, to satisfy another craving.  Both bring you comfort; you're just substituting one for the other.

Hormones.  At our house, we call it the MOANS.  It causes fluctuations in the levels and one result may be that you feel a little blue, somewhat depressed.  It can also cause water retention which can make you feel bloated and unattractive.  Your face can feel puffy and - hey...I don't feel so hot now either.  A little tea.  A little cuddle.  A little music.  A little "retail therapy".  Use it as an excuse to baby yourself - or better yet - let someone else.

i will tell you the exact answer to this, see wat happens is when you drink more of water ur stomach is distended, the thirst centre in ur brain is satisfied, at the same time ur hunger centre is also inhibited so u tend to eat less.... also water helps in faster digestion and more excretion of waste products helping u to lose weight
