I agree with the riboflavin business. My intuition is pretty cluey on what im missing alot of the time and i tested riboflavin using kinesiology-like methods and it was off the chart. Just trying to balance it with the b-vitamins and everything else. I got a MASSIVE headache from taking SAM-e, so i went to my room and lay there, feeling the headache.. once I let it be there and feel the pain, it passed. And the SAM-e since has given me alot more energy. I'm trying to taper off the effexor i'm on as the only reason i'm on it is for energy. The b vitamins, TMG, l-methione and inositol should all help to keep my energy going as i come off im hoping. Dropped from 150 - 75mgs and will test that for a couple of months as stripping the effexor can sometimes leave me bedbound.
