"There’s a reason your doctor will tell you to taper off these prescription anti-anxiety drugs (Valium, Xanax, Klonopin, et al) after taking them for awhile. Each one increases the effectiveness of a brain chemical called GABA, which reduces the excitability of many other neurons and decreases anxiety. Because benzodiazepines cause rapid tolerance, quitting cold turkey causes a multi-symptom withdrawal that includes irritability, anxiety and panic attacks—enough to make just about anybody fall right back into benzo's comforting arms."
