No success stories here, I've only been prescribed Valium (only 4 pills) back in 1979 when my car was stolen at gunpoint (was very traumatizing) my doctor, actually a general surgeon I was going to for removal of breast cysts at that time gave me a 4 tablet script to calm me down, he did not want to give me more because they are highly addictive, and yes both of the drugs you mentioned are addictive and you do build up a tolerance quite quickly, both are "controlled substances". It would be safer to try talk therapy with a reputable therapist, instead of the pills, then see if your doc still feels you should be taking them.
Take care,
