What it's normally used for
Galantamine improves the function of nerve cells in the brain. It prevents the breakdown of a chemical called acetylcholine. People with dementia commonly have lower levels of this, which is important for the processes of thinking, memory, and reasoning.
Galantamine is used to treat mild to moderate dementia caused by Alzheimer's disease.
What it does for Lucid Dreaming
Galantamine is often referred to as the "Lucid Dreaming pill."
Galantamine is even more effective at promoting lucid dreams when taken at WBTB, with Choline, which is a precursor to acetylcholine. By taking these two together, you increase the stimulation of cholinergic neurons from two directions at once.
Not only does Galantamine increase how long you dream, but it also helps with remembering dreams when you wake up.
My own results
I take Galantamine and Choline after six hours of sleep. It's hit or miss on having lucid dreams or vivid dreams. My results can range from getting a massively vivid lucid dream to not even getting more vivid dreams. (Nothing will give you lucid dreams 100% of the time!)
