Same here. Diazepam (benzo) is the ONLY thing I know of that masks 80% of symptoms while in POIS. But for me a 2 mg pills wears off entirely in 5 hours. After 5 hours of taking it, I am back into POIS completely to finish the cycle of 3 day POIS. I have never taken 2 tablets in one day because benzos are addictive, and I imagine very unhealthy overall.
