I blacked out while driving down the freeway, crashed my car, bags deployed, totalled it, with no injuries to myself or other drivers. I have no recollection of feeling faint, dizzy, or anything until I sort of came to on the stretcher as they were loading me into the ambulance. Thank God I did not hurt anyone else. 4 days of testing, scans, nuclear medicine, sonograms, blood work etc. all showed normal. I began taking this med about 4 months ago, and have noticed that a serious side effect posted is irregular heartbeats. Has anyone else had anything similar?
