Hi Mikey. I think many have felt this way.
I finished my 1st round last week with just 12.5 DMSA and felt fine while on the dmsa but crashed on day 5 and still recovering. It's day 8 now and I'm going to delay the 2nd round because I am have such mental symptoms. I really think my adrenals are not taking chelation so well.
btw I tried ala a while back just after having my amalgams removed and had terrible anxiety, feelings of impending doom and the like. I won't try ala until I have a few more successful rounds under my belt.
Hope you figure things out and let us know how you're doing.
