Round worms are busy day and night like that. Pin worms are pretty predictable. They start when your temp drops when you fall asleep. They itch like crazy. Like you have fiber glass in your butt. Probably a mixed infection.Pin x did nothing for me with pin worms or any other worm. Papaya seeds ground up for some reason dislodge alot of them. I did smoothies at first with fresh pinapple, papaya, the seeds, coconut oil. they worked but be prepared to be near a bathroom for a day. Now I take dried Papaya seeds ground up in capsules because i could no longer stand the taste and texture of the seeds anymore.The round worms are tough buggers. Long term strong meds and herbs when your on breaks.
