Keep doing this but I just wanted to let you know that in the original thiamin protocol, lead author asks the participants to avoid any caffeine drinks. Like tea or coffee. Apparently they deplete vitamin b1 or something. If you haven't read the protocol already, I urge you to do that. It can be obtained from a simple Google search. Edit: Also wtf you are not supposed to be taking 1000mg of thiamin. 300 mg I think.
