Ok- so I had one other question- (sorry )- I know that QF 4.0 comes with the little heater but I live in south florida and I'm afraid it's just not needed but- my question is approx how long do I have if I just get it at temp and then keep it close to my...body (I'm a girl):jointsmile:...Would the temp continue to rise or remain level for several hours. The reason I ask is because the drive there is somewhere under half and hour and then they make you wait once they take ur id and you cannot leave that little waiting room until you've given them the sample. I passed once with real "lemonade" from a clean donor and the second time the temp was 102F !!!:wtf: This was a while ago. Any advice on what to do and what not to do during this time to keep it proper?
