Galantamine is good enough, no more than 4 mg. You better take it in the middle of the night and it takes approx. 1 hour to take effect. In my case I have taken it 5 times and in 100% of the cases I have had LD. No one but 2 or 3 of them in a row. Those LDs have come spontaneously without wilding. At least in my case those LD, are not as vivid as the ones that come " naturally", but they are easier to recall anyway.
