anxiety
"I've been on just about every benzodiazapine there is and Valium (diazepam) is all around the best for combating debilitating anxiety symptoms.  It may not be the most potent benzo, but it has wide and equal benzo effects including sedation, muscle relaxation, anxiolytic, anticonvulsant and can be used for insomnia.  Now the main reason why Valium is the best is its extra long half life.  It's effects can linger for days which is helpful if you have chronic anxiety.  It also prevents those ups and downs short acting benzos cause like Xanax and Ativan.  Another thing to note is withdrawal from Valium is by far the most mild out of ALL the benzos.  This wonderful medication is an oldie but goodie."
