I need help regarding weightlifting and stored toxins!

I am around 90 percent recovered. I am 1 1/2 years out of mold. I recently started weightlifting. I am on day three of strenuous muscle exercises, no cardio. I have also been on the carnivore diet for 4 months and been on a methylated multivitamin for a couple weeks which includes enough niacin to give me a small flush.

After my workouts I feel ok but maybe two or three hours after, I feel anxiety and when I lay down I get dizzy. Almost feels like I am falling into my bed. The next day my muscles feel terrible as if I need to constantly stretch them all day. I used to workout before mold and don’t remember this feeling at all.

So long story short, could my body being releasing more mycotoxins from my workouts? Without fiber, I am a bit worried I won’t be able to remove the toxins after a workout.

Any advice is appreciated.
