Highlander, I had issues with galantamine my first few nights. My LDs were short but it was because the insomnia was so bad. Now it doesn't seem to be an issue. My caffeine LD's are usually much shorter and I tend to wake at the one hour mark.

NyxCC, I think green tea would be a suitable alternative if I just HAVE to have caffeine. I've done this before and the lower amount seems to make this a good idea to ween myself off if need be.
