N2, you rock. I read and re-read your tips and guidelines, most of all the part about PRACTICE! Also found great containers and plastic funnels at The Container Store. I practiced walking with that little bottle in my panties, yes, just 'crotched' it, did not insert the bottle into vaginal cavity, and maintained temp at 94. Though I did not see any evidence of temperature testing at the lab. Practiced pouring the substitute into the cup without fumbling and all went well. I started my new job yesterday, and was able to enjoy my last days of freedom flying high! THANK YOU THANK YOU THANK YOU!
