Although the ambein CR was working it left me with intense brain fog and anxierty/depression for the past four weeks so I went off it last night. I also only slept for 6 hrs. on it. I took 3 mg of lunesta which use to work for me and it did nothing. I think coming off the ambein also caused this reaction. Anyways, my dr. wants me to try trazadone tonight. I am just scared I won't sleep again and I am so tired. Any side effects? He told me I may need to take 50 mg but figured we would start with this. I guess if I don't fall asleep after three hours I can take a second one. I am just suppose to take it for sleep not during the day for depression.
