Not directly related to the thread but still I wanted to include this post. These types of studies really make me wonder about the safety of using benzodiazepines for anxiety. I am prescribed lorazepam, but I fear the effects of long-term use of GABAergic compounds on the brain's neurotransmitter systems. GABA clearly plays an extremely role in the brain's ability to communicate with itself and the rest of the body. Messing with it is probably playing with fire. Several sleep aids target the GABA receptor sites as well, ambien (zolpidem) being one of the most popular.
