I modified a pair of shoes for my first test when I subbed to hold my little bottle, it worked well, I think I will use those or an ace bandage holding it on my inner thigh with a head pack, I tried the tighty idea and it didnt seem to work well and I'll have to drive from my place of employment to a remote test site I'm sure so I doubt I'll leave it in all day.

Thanks for all the info, Hopefully all goes well for me
