Hi Teri; Thank you; just wanted to let you know that I saw my Psyc. this a.m. and he did not equate the Pristiq as the cause of stomach pain only. i wii be having office visit with my GP Friday and try to find the cause. May be IBS. Thank You all once again and the prestiq at 100mg takes care of the depression for me now. Which is a very good thing!!!!! Good Health to All!! Sandy
