They work great for me - and I've used Lunesta, Tylenol PM, etc... I really liked these - only problem is that I can't take them too many nights in a row, or else I start feeling kind of zombie-like These are pretty expensive if you buy them in the store - I think they're $6.00 for a pack of either 8 or 16 (forgot) - I didn't want to pay that much.
