I just passed a random using quick fix and a lava pad. before i got tested i practiced by driving myself to the hospital after work and waiting in the parking lot for what i thought would be the time i waited in the hospital. So i was still nervous because i had a timeline but it might not be exact. My boss one day says he needs me to take a random, so i got nervous, then said ok-lets do this. My plan was always to click the liquid reusable handwarmer when i got in the bosses car to go to the hospital and it would be the correct temp in 13-23 minutes or so. Well--------------i clicked it as soon as we got into the car(like itching an itch how scary is that?)and we drove to the hospital. I asked if this would be fast, and he didnt know, saying we didnt have an appt. So i was like shit- this may get too hot! But i didnt wait long at all b4 my name was called so then i was like shit- this may not heat up enough-- but i pulled it out in the bathroom @ 96 degrees. perfect. I know im more confident for my next one.
