Is there something wrong with me?

Ok so I have no idea if these two symptoms are related, but I'll give it a shot. The past three weeks I have had pretty bad headaches almost everyday, it seems to go away with water but sometimes I can't drink enough water to make it go away.. and I mean I would have to drink a lot. To me, it seems like I shouldn't have to be drinking more than the average person would drink you know? The other thing is for the last week I feel like I have been digesting food really funny. I wake up and my stomach is gargling like mad (not that it hurts or anything) and then after I first eat something, I get a stomach ache and by my last meal, I feel pretty awful.
