Yes, I have had this happen to me two times. After a lot of testing, we just found out mine is related to Sugar levels also but I never had this happen prior to mirenda iud. The scary part of me is once it happened to me while I was driving. Thank god the kids were not with me. Yes, I went out and I had a head on collision. I woke back up on impact. I felt it coming and I tried to get off the road. I know I came to a complete stop but didn't get the car in park before I went out. My foot came off the break. This happened about a month ago and it seems to get worse for me at the same time of the month every month. I don't have periods any more so I'm not sure if it is happening during my period or not. If you are having this side effect, please get yours removed asap. I'm lucky to still be alive!
