Why can't you take Benadryl several times a week? Trouble waking up in the morning? It seems to work well for me.

Another solution might be taking a small (25-50 mg) dose of Seroquel before bed PRN. That seems to keep me asleep if I'm waking up at night & am unable to fall asleep.

As the daylight hours grow longer, I seem to have more trouble getting a good night's sleep, but I think that's just my schedule. During winter daylight hours I tend to hibernate like a bear. I hope you can find a solution to your insomnia. I'm not having this problem right now, but know how frustrating it can be.
