Anyone else have severe reactions to DMSA that lasted for a long time after stopping?

It's now been 5 weeks since I last did DMSA. And by "last", I'm talking literally only my second round. I am thinking that using 25mg was not wise.

I have been sick. Throwing up a week after I stopped the round, and having stomach issues (ranging from reduced appetite to feeling sick or like I might throw up) on and off for over a month now. I have not had these types of problems at ALL before I did DMSA. I want to know when this crap will end, and how to end it faster.

Is it related to detoxing? (It seemed to get worse yesterday after I'd used Lugol's Iodine the day before, but that could be a coincidence)

Has anyone else here been through something similar - if not stomach illness, than another issue that took forever to resolve? Who here has had DMSA backfire horribly on them and taken a long time to recover? Do you have any advice? The advice I'd been given hasn't been helping.
