I had a parasite called crypto for short a few months ago..i delt with having the shits for to long,finally went to dr. And did stool sample and bloodwork. It was most likely from unwashed fruit or veggies, it got bad towards the end,I couldn't go for 30 mins without having the bloody runs..pains,scared to fart etc...
Anyways I took 6 pills over 3 days,I would have to see what it was ,I don't remember, doubt I could spell it anyways, I'm better now,long story short,don't neglect your digestive system and definitely don't be a stubborn asshole like me..
