As such, I have next to no tolerance. As great as having no tolerance is for the productivity benefits, it does have undesirable side effects. A single cup of coffee can get me twitchy and slightly shaky, and a cup of tea past noon can impact my ability to fall asleep.
A gripe I have is the lack of good research into the combination of theanine and caffeine, and I think I'd be a good candidate for a blinded test looking into it. I would like to carry one out but really do lack experience in tests of this nature.
Does anyone know any good resources for someone interested in learning how to conduct a self-study such as this, including details regarding common pitfalls?
