I have taken supplements that have helped me personally to certain extents. These include, with results purely based on my own anecdotal experience, in order of most to least effective include: - Phenylpiracetam: A cognitive stimulant that helps me choose substitute words much more quickly - Taurine: A supplement often used for fitness purposes that reduces my hard blocks - Modafinil: Can go both ways, either overstimulates the thought process and make blocks more severe, or raise confidence to a point that blocks are significantly reduced - Caffeine and L-Theanine: Mild to no effect - Vitamin B1: No noticeable effect
