Tom..I took Pamelor in 1996 thru 1999, and although it helped with spasms of the colon, I was still constipated alot. The med you are currently taking is similiar to the Pamelor, it can be constipating also. My problem with the Pamelor was weight gain. Also, I craved sugar as it warned. I am taking 37.5 mg. of Effexor before bedtime and I have had marvelous results with IBS, GAD, and depression. I don't wake up feeling like I haven't had anything to eat for days. Therefore, I am able to control my weight better. At first when I started to take it, I felt tired during the day, but that side effect is wearing off now. I'm not saying it would work for everyone, but I've tried so many, and I feel this is the best choice I have made for myself. Are you having sleep problems along with the IBS? I was put on the Pamelor to help with lack of sleep due to major depression after my husband shot and killed himself in 1996. The effexor helps with sleep.
