My son developed an addiction to street valium 10 years ago aged 14. Hes been struggling ever since. 5 years ago the GP prescribed 120 mg diazepam daily and very gradually reduced the dose. Whenever he gets below 50mg he feels awful and starts using other stuff as well as street valium. He currently collects a daily prescription of pills and methadone but this is still not enough. At the weekend he took 100 street valium..... not unusual for him and he does it to try feel normal. It must have been a bad batch because hes been I'll and very sick for 3 days but refuses to get medical help. I'm out of my box with worry. Help please
