Thanks for the info, guys. I had planned on taking some vitamin B and doing dilution.

I took another one of the CVS tests yesterday afternoon, and it came out negative.

I also ordered about 20 or 25 strips from a place online that somebody posted here. I tested the first part of my stream just now (9 days after the last time I smoked) around 6:30PM, and the line that shows negative was so faint, that I can't tell if it would even count as negative. It was so faint, that unless I knew that it was supposed to be there and really looked for it, I wouldn't have seen it. I then used a strip in plain old water just to check it out, and both lines came in pretty bold. That tells me that the line CAN come in a lot less faint.

I'll try dilution on my own next, and I will report the outcome. If dilution doesn't work at home, then I'll just go for substitution and hope that I don't get caught or have to chang clothes or something.
