The reason I was on mirtazapine was that it helps me FALL asleep, which is the thing I've had trouble with my whole life. (Honestly? I've been an insomniac since I was a small child. I was prescribed valium at the age of 18 months because my mother was so desperate to get me to sleep, although she was sufficiently freaked out to find a new GP rather than feeding me pills.) Trazodone is also supposed to help with sleep, but it seems to be doing precisely the wrong thing. The first night, I was still awake 6 hours after taking it, and getting increasingly desperate about my ability to get enough sleep before work. Last night, I was still awake 3 hours after taking it, but eventually fell asleep naturally. Then I crashed out for 13 hours and woke up with such low blood sugar that I could hardly get out of bed to find food. (All my body wanted to do was to go back to sleep, which I know from experience is rather dangerous, because then my blood sugar gets so low that I can't wake up by myself at all. It takes someone putting sugar or chocolate into my mouth before I can wake up). Currently, it is about 3 hours since I took it, and although I'm tired, I don't feel sleepy. I'm not convinced that I'll be able to fall asleep if I get into bed and turn the light off.
I can take "2-3 capsules per day", so I could try 3 capsules instead of 2. But I'm not certain that won't make the staying asleep too long worse, while not touching the inability to fall asleep at all. Waking up exhausted because of low blood sugar sucks.
