after 10 rounds of ALA Andy says you should notice an intellectual change....meaning that you can tell your brain is functioning more properly.
I personally end rounds with a few doses of DMSA only to help mop up the mercury pulled out by ALA. Sometimes I even do a whole day of DMSA only. Andy said this was ok.
If you handled it well, and recover fast, I would stick with this dosage. See how you feel in a day. Otherwise maybe try ~17mg ALA (which would be 1/3 of a 50mg capsule, or 16.66).
