After a very successful week stretch at 10mg daily, I'm starting to notice that about 6 hours after dosing, I get really tired, and the most obvious benefits seem to wear off. I've tried going above 10mg, but it's just too much at this time. I get brutal headaches, start sweating, and get really agitated. 8-10mg gets by okay. Is this just due to the half life of methylfolate? Should I break the 10mg into multiple 2mg doses every few hours? Will that feel as effective?
