i think them equivalency charts are inaccurate, from my own personal experience. It says that 10mg of valium = .5 xanax/.5 klonopin.....i have been on Klonopin, Xanax, Ativan, and Valium throughout the years, and when it comes to me taking a .5 of xanax, i feel NOTHING, when i take 10mg of valium, i do feel SOMETHING alot more then .5 xanax. for what it's worth my doctor, whom is 61yrs old, been in the medical field since the late 70's; told me that 10mg of valium is right around equivalent to 1mg of xanax/1mg klonopin. Im on valium right now, he tapered me off of 4mg daily xanax by using valium, and with that experience im confident to say 10mg valium =1mg xanax...along with years of being on benzo's...listen to ur body not the charts
