Just want to point out that I got the human pills of ivermectin and mine are working well. I had been having some weird feelings all week but I tried not to turn into a hypochondriac by thinking about it all the time. By Thursday night I realized that this is what I had prepared for and waiting longer would be really foolish. I could tell like Karl that my heart was working way too hard while I was lying in bed. I got up and used the O2sat meter to confirm that was a bit low for me and then I took my first dose of IVM (a .2 dose) at 3 am. In the morning my oxygen was much better. Last night I upped it to the .4 dosage. I also took my first fluvoxamine this afternoon. Lots of side effects from the fluvoxamine but none as far as I can tell from the IVM. Breathing seems totally clear now after less than 48 hours on the IVM where before there seemed like there was some very light resistance.
