I don't know what to do. It really helps me sleep and klonopin didn't. The other night I was scared when I thought it wasn't working but it finally kicked in. Last night it finally kicked in. I will take it today even though it makes me more tired during the daytime. I don't know what to do. I know how important sleep is and how deprived I was but I have no energy. I missed the appt because I relied on the phone call reminder than than checking the date. I will start checking the date from now on and put up with the tiredness. I probably had the ac on for two and a half weeks, My bill last month was 120 dollars and I didn't use it as much.
