I take 40mg a day of Prozac, 50mg of toporal xl, 10mg of ambien at night, daily vitamins, And Xanax as needed. I get severe migraines every so often and my Dr prescribed Maxalt mlt 4mg and Zofran. I took the maxalt and Zofran Thursday afternoon and Friday morning. My migraine is gone, but I've been feeling dizzy, tired and foggy ever since. I've read about Serotonin Syndrome and now am completely worried. I suffer from postural orthostatic tachycardia syndrome and don't know if my symptoms are from that or not.
