I am currently taking Effexor 150 mg/day, neurontin 600 mg 3x/day, seroquel 25 mg at bedtime, and adderall 15 mg 2x/day. Adderall is the newest, I have been taking it for about 2 months. Over these months, I have noticed a big change in the frequency of my bowels. Almost like diarrea every day. Could this be from the adderall or has anyone ever experienced this? I am having a lot of marriage problems lately, and my nerves have been bad and I internalize my feelings a lot, and I'm thinking that is why - maybe IBS symptoms? Just wondering if anyone knows or has had this experience with adderall. i need to take it though - its helping my ADD symptoms so much, I would hate to stop it
