Pickles, celery, and SF jello save me. Plain old ice water is really good (compared to room temp), but adding some flavor to it is good, too. It makes you feel like you had something more substantial. I usually take an old 2 L bottle of soda and make Crystal Light lemonade in one and iced tea in another and keep them in the fridge. I mix them up sometimes in the cup, other times, just pick whatever flavor sounds good at the time.
I felt the same way as you, so you aren't doing anything wrong.... It gets better
