Great question! We are actually running a study on this right now! Galantamine is an over-the-counter supplement which increases acetylcholine in the brain. Previous research has found that galantamine increases lucid dreaming (LaBerge et al., 2018). In that study, they found that 8 mg of galantamine was the most effective dose. You can also look at this book Advanced Lucid Dreaming by Thomas Yuschak, which describes a specific protocol for taking a choline supplement before galantamine. It's important to remember that galantamine should only be taken after a wake-back-to-bed around 4am, and it can sometimes make it harder to fall back asleep. Therefore, I would only take it on a night where you don't have to wake up early the next day. Also, there is research showing that galantamine supplements vary a lot in their quality (Cohen et al., 2024), so I would encourage you to research the supplement in advance and only purchase from a reputable vendor.
