Mebendazole experience -anyone who has taken it?

I took it because I read a paper on Dientamoeba Fragilis which said that it is not known how this parasite survives stomach acid and gets into the system. It is thought DF hitches a ride on pinworms. It suddenly occurred to me that I didn't know if the drugs I took for DF (Iodoquinol and Doxycycline) would have killed pinworms (not that I ever saw sign of them - but that doesn't mean anything). When I read on the internet that you can take a larger dose of M to kill whipworm, roundworm and hookworm and could get it without prescription I thought I would give it a go. I took 1 tablet twice a day for 3 days. I thought I passed a worm. By chance I had colonics a few days later. I didn't have bad reaction.

I planned to do the follow-up treatment 2 weeks later to kill eggs etc. Then I read Rabbitears with warnings about this drug saying that it caused the migration of worms to other parts of the body. I was so alarmed by this that I only took one tablet and then stopped. The following week I got unusually bad aches in my legs and back and bad brain fog. I was imagining all kinds of things. But I kept thinking that these were just my usual food reactions only worse.

I had to travel abroad for 4 days. Immediately all the pains and fog vanished. I was then back in the UK for a week – once again eating my usual restrictive diet and the aches came back immediately. I took drastic action and cut out all fruit/ACV. I went abroad again and the aches/fog disappeared again.

This is just my experience and I am very interested to know exactly what happened to anyone else. Did you take the single dose recommended for pin worm or the larger dose for other worms?. How dangerous can this drug be if it is passed by the FDA?
