I would say just try ervything for just a week or two and see your results, I am sure that money is tight as it was for me, if that is the case my advice would be to first buy the Reacta-C and take that in large doses, and put the mineral oil mixed with mint or tea tree oil on your body. then just buy some two dollar sheets at walmart, try changing them for at least a week. you will eventually see what works for you. Also I have read about a drug called ORAP that seems to help people, this is a sedative, however, it may work because if it is strong enough to sedate a human, it may be harmful to the bugs as well. the biggest thing is don't give up, have faith and keep working until you are cured from this.
