@Pungent agreed. Each person must decide for themselves.
Galantamine is interesting to me because it is currently used (prescribed) for other brain-related things, such as treatment of cognitive decline in moderate cases of Alzheimer's. The fact that it has such a positive and dramatic effect on my sleep and my dreams makes it doubly appealing (for me, for others it may not have the same result or benefit)
YMMV. 🙂
