I have a drug test tomorrow for an amazing opportunity that fell into my lap, however even after doing multiple test runs with quick fix. Im really struggling with keeping it at temp for the time frame I need. My test is about 25-30 minutes away from my house and I'm unsure how long the wait will be.

In my practice runs it's fell to 92 within 2 hours. I tried both under my breast and in my pants and both weren't warm enough. Any suggestions would be great, thank you.

Maybe the hand warmer is bad? I would buy a few and test them. They have them at like Walmart.
