That’s hard to say cuz while I’m taking those things my symptoms become the most agitated and my entire world becomes a complete nightmare and I haven’t taken either diatomaceous earth or garlic since I got prescribed albenzole because I honestly just couldn’t take the torture anymore if your only concern is IBS and not parasitic then you souldnt have to much to worry about it would just be mucus that your body is creating either due to constipaton or a possible bacteria infection (which I as well have been fighting off for some time now). I didn’t become worried about parasites until I actually saw one (I’m not saying I ruled it out just wasn’t concerned).
