I received the 441 IM injection and was told to take 10 mg/day orally for 21 days. So far the side effects are horrible. I have told my psychiatrist but with the shot I am stuck for at least a month. How long do the side effects last for people? Furthermore, my Klonopin no longer knocks me out like it should. I was prescribed Ambien to help with sleep during the side effects phase but the horror stories mean I haven't taken it yet.

So my question is how long does the drowsy all the time, can't sleep at night, bad appetite stuff last?
