gutpile2, it sounds to me like your kisser is turned so that the opening in it is towards your face. If it is, the open edge where it slips over the string is catching you in the lip.

I have not used a kisser for over 10 years, but I remember that lesson clearly!

Make sure the opening is turned away from your face when you come to full draw.

If that doesn`t do it, I think WV Hunter may be right.
