I think about this quite a lot myself as well. I take Prilosec for acid reflux, but hadn't heard anything about it helping to digest food - I just thought it was to control heartburn, hehe. I decided that maybe I wouldn't need it if I ate healthier, instead of just eating whatever I craved with the mindset being that any food was good food for my skinny little body. I tried going off it and adjusting my diet - didn't work.
I also take a medication called Megace - anyone heard of or taking this? It's used to stimulate my appetite, but it's a hormone and kind of messes with your system a bit. I went off this when I decided I might want to have children some day. I immediately lost a ton of weight (well, not a ton, but you know what I mean). I don't know if it's psychological or physical, but my appetite is TERRIBLE when I'm not on this drug. Even thinking of food makes me feel nauseous <img src="i/expressions/face-icon-small-disgusted.gif" border="0"> When I do take the drug, I want to eat everything in sight.
So I guess my point is, that yes, I do think about long term affects and struggle with that whole "there must be a better way" thing all the time. I have tested the waters where I think I can and have found both times that the meds work better than anything else.
I'm content taking all my medications - I want to live as long as possible, number one. But I still do think there must be a better way, LOL <img src="i/expressions/face-icon-small-tongue.gif" border="0">
