Yes, I have had blackouts related to severe bipolar episodes a number of times. Honestly, I only remember five to six of my 10 psych hospitalizations, or barely bits of the others. I even have no recollection of most of the time that passed severely depressed in Taiwan before they took me to the hospital there. [Maybe just one night when there was a sizable earthquake, which I just stayed in bed during and never got up. I guess I sometimes went to the bathroom.] And though I remember most of my time in Hong Kong and Thailand, I did black out during some key events. For example, I have zero recollection of how I made it back to Bangkok from the island of Koh Samui. I don't recall a boat ride. I don't recall a bus ride. I just remember suddenly "coming to" at a police station there where I reported being pickpocketed of most of my money. The police report was necessary inorder for me to get my American Express traveler's checks replaced (for those here who remember what they were).

I have also experienced fragmentary type dissociative amnesia, which may be about the same thing as bipolar blackouts, but my bipolar ones were more like en bloc style. I differentiate between them only because some happened when I might not have been in severe bipolar episodes. Those, I think, were during a period I had of frequent maladaptive daydreaming. As someone also mentioned, during one I had an out of body experience. Or was that a focal partial seizure? I don't know.

I have also had about five alcohol blackouts. Three of those are horrible to think about, and may have been exacerbated by bipolar episodes. I know I went on a business trip during one, but I did not attend a part of it. I don't remember what city it was in or if I was missed. I do remember being at the bar at a point, likely drinking gin and tonic, and then suddenly walking down the hotel hallway holding the hand of some strange man. I remembered waking up with a hangover of a century. No clue about anything else. I don't remember anything about my return home. Maybe I was manic!

It's possible that some of the injections I received at the hospital caused blackouts. I vaguely remember being dragged to an isolation room, often screaming, several times and given injections. I remember being in there some of the times. I remember a couple of times assuming I had been in there because suddenly I "come to" at 6 pm when my husband visited. He found me sleeping in my down coat in the ward's common area. He told me later that the nurse begged him to help get me into the bed. Apparently, I had freaked out about the room and became out of hand. Another time I remember "coming to" to find that I had my own room on the ward. When I attempted to leave the room, a security staff member followed me around the ward. He was stationed outside my room, sitting in a chair for (some period of time?)
