Dont worry be happy.......get the temp up to 98...
I did it today at lab corp.....they do not watch you and you can lock the door..no waist band check or anything ..they make you wash your hands before and after.....if you have 2 hours then I would use hand warmers ..it worked perfect for me.....as long as the synthetic works ..and I asume it is like 100% from what they say here.....you will have no problem....just check temp before you go in.....it is 90-100 you pass !!!! good luck.. and we will welcome you to the sub club .....I even smoked one one the way down there....I wore nice clothes that heps take the suspicion off..be freindly...but not too much....it took 2 hours to reach 98 though.
