Honestly, I only have 4 days until I use it and I am 99% sure I am just over worrying. I totally appreciate all of the advice and I hope you understand my paranoia. Burnt, can I buy those at a drug store to avoid waiting for them to be shipped? Also, do the regular tests sold at the drug stores check for validity and/or adulteration?

Thanks again, I'm super paranoid, but I truly appreciate the advice.
