It worked great until Friday night Feb 19/16. I was not able to sleep through the night and the nightmares came back. Same thing happened Saturday night. Sunday night I was up and down to use the bathroom (#1) at least 6+ times and every time I tried to go back to sleep the nightmares would start again. I do not drink or eat any thing with caffeine after 3pm. I see my psychiatrist on March 1 and I am wondering if he may need to up the dosage. Any advice would be appreciated.
