I was just wondering if anyone has had diffuculty taking ADs? I'm trying to take them & can't seem to find one that doesn't kill my stomach. I'm having headaches all the time, chest pain & problems sleeping. Plus IBS which is not all that bad right now. The last suggestion was to take a Zelnorm before I take the AD. Seems silly to take a pill so I can take another pill but I think I'm going to have to try. This is killing me!
