Update:
Today I decided to try drinkin gatorade (non watered down) instead of my 2 glasses of water in the morning.
And today Ive noticed much less urination and I was only needing to go about once an hour iearly in the morning instead of 30-40 mins. And keep in mind that it was super cold this morning and that usually worsens the situation.
I would have figured that i would have been getting enough naturally occuring sodium in my diet, but maybe I really am not getting enough sodium.
my appetite increase my be a result of a desire of sodium because I alost never add salt to anything and I don't eat salty snacks regularly. maybe overeating was what gave me enough sodium throughout the day too.
Stop drinking so much water. It's doubtful you would have a real problem if you are drinking normal amount of liquid and not trying to use water to affect your appetite. You don't need as much water if you cut your sodium intake, or vice versa. If you have a weight issue, tackle that directly through calorie cutting and exercise, the two proven methods of weight loss. Gatorade isn't a sodium supplement either, by the way, it's just a small amount (usually less than 200mg a bottle) and partly offset by potassium.
I'd recommend drinking green tea to help with craving control if you really want something with zero calories to drink or sip on after breakfast and to help a little with weight loss, but that would make you urinate more (it acts like a diuretic, as does coffee and other caffeinated beverages, in addition to being mildly thermogenic). If appetite is your real problem, get more fiber in your diet. If you have a truly healthy diet with a lot of leafy greens and other vegetables, fruits, whole grains, etc, just the low calorie and high volume nature of those foods should keep it in check. Aim for 1,800 to 2,000 calories a day, not 2,500. You would be surprised by how much food 1,800 calories is when it's veggies and fruits (preferably raw when possible, or at least minimally processed) making up the bulk of it.
A "nature valley fruit and nut granola bar" isn't that great an option, either, as it's mostly just sugar (carbohydrates), and it's not that filling. It's good snack for energy if you are hiking or doing something else that burns a lot of calories and need a small snack, but it's NOT the basis of a good diet. Granola in general is calorie dense and not the best option for maintaining or losing weight. I don't know what else you are eating for your meals throughout the day, though, but 2,600 calories means it's probably not as healthy as you think.
I switched to a vegan diet 2 years ago (for more reasons than just weight loss, but that is one reason out of many) and my weight went from 215 lbs down to 187 lbs without much effort at all, most of it occurring in just a few months after switching. All that fiber rich food is filling. Currently limiting my calories to 1600 to get it down to my goal of 175 lbs. You don't need to become a vegan to fit more vegetables and fruits into your diet, though.
P.S. Go ask your doctor about all this. I highly doubt it's diabetes insipidus. Drinking a lot of water just makes you pee. Relatively simple, and I bet he/she puts it the same way.
