No dosing during our vaca. Dosed up until the day we left, .500 mcg. I respond REALLY well to MT2 albeit I still get nauseous from it, but Im really happy with the outcome. I get dark enough where friends do a "doubletake" when they see me. For anyone wondering, once I stop the shots, the tan last for 2 or 3 months and slowly fades away in the winter. The moles return to a lighter color also. I have no lingering effects as far as I know. The only concerning thing Ive seen is a few moles popping up that werent present before. other than that, no problems.
