I take a combo of meds and I wake up feeling sick--like I want to vomit. I have noticed it helps if I eat a little something before I go to bed--not too much, just some toast or something. Then, I am like you I get up, drink a coke and take my meds and it fades away.

I am not a doctor...but sometimes I wonder if my body is going through a little withdrawal from the meds because after they kick in I feel okay. I don't know--that is just a thought.
