I should have been more specific. What I meant was that do your WBTB as normal. Only take the Galantamine pill just as you go back to bed again. I usually combine it with 200 mg or so L-Theanine to fall asleep more easily.

Also on the clarity, it depends and varies from dream to dream and person to person. You can increase it once in the dream though to levels even beyond reality. You can see further, more crisp and experience colours way more vividly. For me that lasts only for as long as I focus though. Some dreams I've had have been so incredibly vivid that I questioned if I wasn't infact awake.
