insomnia
"I wanted this medication to work so bad - I got all the side effects except no sleep :( . For me it started working after only 10 minutes of taking it, and yes it does give a metallic taste. The biggest thing, hang on for a crazy ride! It made me VERY relaxed and have mild hallucinations (the blinds on the window and my bedroom door would look like they were slightly moving open/close or back and forth). Im not sure how, but sleep never came! How I could be in that state and not sleep is beyond me."
