Aw hell.......why don't you just take your shirt off!...lol. I've been thinking that if you've got a lot under your shirt....what's in your pants? Maybe one day I'll get to see that too??

Usually one dosage kills all the parasites and the second dosage is just a procaution (or so I've been told). The standard dosage for the 3 major drugs that kill parasites is once and then again in 2 weeks. If you've done that you should be fine.
