I have had problems over many years sometimes taking more medicine than I should have without knowing about it. The effects from these overdoses were obvious to my family immediantly. They do not happen very often and they haven't ever required medical attention. I have been taking Ambien/Ambien CR for several years now. I switched from the regular Ambien when the Ambien CR became available. Two nights ago I took my nightly migraine medications and my Ambien CR. I remember being awake for about 45 mins after that and then I remember nothing. Some how I was unconscience when I took 8 more Ambien CR 12.5 mg. I remember nothing after that. I went on a wild rampage in my room and destroyed everything in sight and I do mean everything. Then I managed to get to the Living Room where I fell down and entire flight of steps and a neighbor had to come rescue me because I was screaming bloddy murder. Then 911 was called and I was taken to the ER. All of this info was given to me later because I do not remember anything from that day. Not the destruction, not the fall, not the hospital, not coming home, none of if. What Happened??????
