Question about Seroquel?

I'll be asking my doctor about this as soon as he is in again tomorrow but in the meantime - I started low dose seroquel last night (just 25mg) to see if it would help me to sleep, and I'm not liking it at all.

I spent the first few hours feeling very agitated and was pretty well bouncing off the walls, then I crashed out completely for an hour or so. Today I am lethargic, dizzy, falling over (which takes a fair effort given that I am in a wheelchair!). I'm aching like crazy from all the falls too.

Has anyone experienced anything like this, especially on such a low dose?

For the record, we've already tried all the more conventional drugs to help me sleep and nothing works. I'm in very severe pain, and haven't been getting more than an hour or two of very broken sleep - basically, I haven't slept in about three weeks, haven't even been to bed for five days, so we're getting a bit desperate.

Any help would be greatly appreciated :-)
