Hydration for Morning Workouts

Hey guys,

I'm a full time university student and the gym we have here is packed all the time shortly after opening. I used to go to the gym after work when I wasn't in school and I liked that much more, I was hydrated, had fresh carbs and didn't have a full stomach.

Anyways, the problem I've been having is dehydration in the morning. I've been staying hydrated the night before but after about 6 or 7 hours of sleeping I feel like that hydration has diminished. I start the morning with a glass of milk (+protein) and some cereal and then drink water consistently at the gym itself (leading to a really bloated feeling). This doesn't do the trick at all... I still feel tired and during leg work outs I almost feel sick with all the fluid sloshing around.

I understand it takes hours upon hours for hydration effects to kick in, so what have you guys found is the most optimal way to hydrate before the gym in the morning. Should I wake up in the middle of the night and drink a glass of water?

Thanks a lot!

P.S. I know I can always wake up earlier but again, being a student really cuts down on time - which cuts into my sleep.
