Oh no, you're hitting that time. It is horrific. But yeah, you don't have to take the DMSA. DMSA done andy's style is the safest I know of to clear this dumpage out faster and sometimes can help symptoms (not always), but it's optional.

The body can do this on it's own over time aided by the diet. It's much slower, but maybe all you can handle at this stage and you have to listen to your body and how much it can take at onetime. It may only be able to do it over time.

Alpha lipoic acid is actually the one that is needed. DMSA isn't. ALA is the one that will chelate organs and brain, but it is not to be used until your body has first drained the fast pools of mercury (which is what you're getting now). So your body will need to go through this first for a few months and later if you feel like it, yu could start using ALA. Available in any healthfood shop.

If you dont respond well to DMSA, you may have to forget it. Not everybody does ok with it. ALA is the one we really need anyway. Some choose to use DMSA because they want to reduce their blood/tissue levels of mercury faster than what the body is doing on it's own and for some people though it can cause worse symptoms, other times can suppress them too and help them feel better faster (not for all though).

THen later, they add ALA. Like you, some choose to omit the DMSA, let the body drain out the fast pools of mercury on it's own gradually (as painful as it is). Later, when blood/tissue/urine is lowered (takes months), ala can be used to then start chelating brain/organs.
