ALA chelation giving me crazy brain symptoms..

I am just finishing up my second round of chelating with ALA and DMSA. Before this I did 5-6 rounds of DMSA alone. Holy Moley is ALA making me feel nuts. I swear I feel like my IQ has dropped 30 points, and even like I have amnesia sometimes.

Of course this can't be normal. I am only taking 25mg of ALA every two hours. Has anyone else had such noticeable brain chelation symptoms from ALA?
