Pre-MEPS Preparation?

Hello, I am going to MEPS on thursday for the United States Army. I went a couple of months ago and didn't make my abdominal tape, I was REALLY close. I have lost about 30lbs since, and about 3 inches on my abdomen. I know all of the tricks, bath salts, prep-h, diuretics. Anything else that might help me? I was taped by my recruiter last week at 37" and I need to be under 38". I stick to a healthy diet and workout via Crossfit. I think I'll be fine but I'm just concerned about failing. Is there anyway I could quickly drop some inches around my abdomen\gain on my neck? THANKS!
