I just started taking Paxil for my IBS about a week and a half ago, and am still at 10 mg a day. I have noticed some help for my IBS symptoms, but at the same time, have felt rather run down and easily exhausted while taking it. I also have had some panic attacks in the past, and it seems like I am having moments of panic now MORE than before I started on this medication, which doesn't make a lot of sense to me. I was wondering if anyone had similar issues, and if you think it may just be something that will last the first few weeks as I adjust to it, or if this is a sign that I really am not reacting well to the medication and should talk to my doctor about getting off of it. I had taken Bentyl for about four years and it stopped helping me, I've been having a bad flare up for the past two months or so, and my doctor decided to switch meds.Thanks for your help!
