I know people probably know about this but I cannot swear enough by vitamin B1. I keep it in the bathroom cabinet and take one whenever I am feeling anxious or depressed. Of course it is not an immediate end to your worries but I find it boosts your mood and makes you stronger inside and think more clearly. It is often given to alcoholics when they withdraw from alcohol. I wonder why it works so well for me? When I take it I also get a better nights sleep too! My diet is healthy and does not seem to be defective in this vitamin but when I take an extra tablet of it a day it certainly has noted benefits for me!
