Acetylcholine also is what is used in one of the lucid dreamers supplement of choice galantamine. I'll probably find a few more things and report them here but if you guys find a flaw in this make sure to let me know.

Edit: Galantamine does not contain acetylcholine but it prevents the breaking down of the chemical.
Dopamine breaks down very quickly in the brain. So unless you go to sleep right after you exercise I doubt it will have any effect at all.
