The day 2 of dosing Moxidectin, before I took dose two, I had severe heart arrhythmia. Took potassium in the form of coconut water (1400mg)and in 20 minutes I was back in rhythm. So I tend to think that moxi pulls the potassium out of the body faster.
I've always had a potassium shortage and had a stroke at 24 because of it. I believe it is caused by the parasites.
