I went on the lexapro for mainly anxiety with a bit of depression. It is primarily prescribed (as far as I know) for anxiety. I had been on it previously but only 5mg and that wasn't enough. I wish I knew then to increase the dosage, but instead I went off of it, suffered for another year, and finally went back on after reading that others here take it in higher doses and it helps them. My doc said that it might help with the IBS but I didn't expect it too since the 5mg did not. Now it does make me a bit c too but I'm also doing the diet whereas before I was eating triggers and taking the 5mg so I was still getting d. I read the other post about Elavil precautions. I hope it remains successful for you and doesn't affect your weight or anything else. If it becomes a problem, don't fear...maybe you could try the lexapro! (I'm not usually a big medicine advocate, but like you I felt at my wits end with the IBS "dictating my life" as you put it. I think the hypno helped me with that too.) Well, enjoy while it's good.
