Started ambien because of chronic insomnia and restless leg syndrome. My doctor found I was anemic and said this causes restless leg syndrome and I also have fibromyalgia. Ambien gave me relief. However, over time I began noticing things that concerned me. I have always been very sharp. Mentally sharp. Great memory. Very business oriented, etc... But that all started to fade away. I was on ambien about 10 months. I was having huge problems with my memory. My mind was no longer sharp. I would forget the simplest things like my phone number and then feel a moment of panic before I'd remember it. Also noticed I didn't remember many things that happened the night before. I felt I was making mistakes that were very out of character for me. My hair got very thin. Seemed like a lot fell out daily and every time I washed and dried. I was scared I was going bald. I kept wondering if the ambien was causing hair loss but couldn't find any info on it. I was having a lot of stomach troubles, every single day, multiple times a day. I went off the ambien to see if it would help me get my mind clear again and see if my hair stopped falling out. I notice that without it I have the same insomnia I had before. The same twitching legs. So it's hard to go without it. Yet I have been off of it for 11 days now because I can tell a huge difference in my mind. The memory seems to be much better. I haven't had any ibs since I stopped taking the ambien which was a huge and pleasant surprise to me. I had no idea the ambien was contributing to that, but apparently it was. Last night was hard because I slept none. I don't know which is worse, the conditions I have without the ambien, or taking the ambien which creates different issues...
