Gabapentin helps with sleep? That's news to me. But then again, I'm on it for migraine pain so it's probably different. My dose is much higher (it was 6x what a friend who took it for depression was prescribed) and I take it in the morning and at night.

Seroquel, I can definitely attest that it works to help knock you out. Granted I'm super sensitive to side effects but I looked/acted drunk on it, worse than with Ambien even though it was just like it was when I was on Ambien. Seroquel ups your blood sugar levels so if you have a family history of diabetes you shouldn't take it (which I found out later).
