I'm glad that you're seeing progress, but please be very careful, you can get worse if you don't take ALA on it's half-life due to mercury redistributing to sensitive organs rather than being excreted. Look up Andy Cutler Protocol if you haven't already.
Also did you check to make sure you got rid of ALL the amalgam? alot of dentists might accidentally leave specks of amalgam in and if you take ALA with amalgam still in, even just a teeny-weeny speck, you can make yourself alot worse. The ACC group recommends people take 4 intra-oral bite-wing X-rays and they have a number of dentists who give up their personal time who will check them for amalgam specks for free.
Yea, i see very nice progress with ALA, just found on Andy Cutlers chelation Facebook page you mentioned that we must avoid high thiol foods which can move mercury and have a strong anxiety, amazing, every time i eat meat, cheese, hamburgers/cheeseburgers, full of thiols, the next day is a mess in my head, anxiety, even got crying, especially after sex, when i fast for 48 hours everything is almost ok, so no more Mcdonalds, pizzas and junk food with ALA, fasting and ALA only and salads.
Anyway i'm doing coffee enemas for a month, it really helps, i started putting 1 tablespoon of baking soda in enema, started to feel even better, but with ALA i started sometimes to feel like i have no symptoms in a few moments, amazing, but with no junk foods at least for a 1 day.
I have no amalgam present in my mouth, i did xray before removal, amalgam was not to deep in tooth, i asked dentist and she said every speck of amalgam was removed. But i see that i will never know until i made another x ray of that tooth.
So for now will continue with ALA (started with 600 mg, 5-6 times a day every 3-4 hours like you said) and with fasting, i started taking activated charcoal when i started ALA, i hope that also help, also taking diatomaceus earth on daily basis 3x of 1 tablespoon trough the day, just for maybe accidental parasites in the gut, taking vitamin c - mega doses, b1, b6, b12, b complex vitamins, selen, zink (huge benefits), i read that mercury depletes zinc on that FB page, amazing, today i started with Zeolite as i read it is a great binder and will surely look into more detail of that protocol (DSMA etc).
It will be loong journey of detoxing.
How is DSMA helping you?
Hope you doing better every day!
