anxiety and stress
"Vivid dreams/nightmares alternating with insomnia. Jaw clenching, teeth grinding at night. IBS like symptoms. 
Short term memory loss was the most disturbing. I would be right in the middle of a sentence and everything would drop, I would stop and have to try to remember what I was talking about or what I had wanted to say which was both embarrassing and upsetting. By the year end on this medication, the side effects completely overtook the benefits of this medication and I stopped."
