Definitely! After LSD use I felt so unbalanced trying to fit in with everyday society I ended up becoming a barbiturate addict and was taking Sodium Amytal, Tuinal, Nembutal and other downers. I had fits and my parents discovered I was a drug user. I was sent by the family GP to a psychiatrist who was unable to sort out my problems and I was put on Valium (Diazepam), which was the start of a seven-year addiction. In that time period I suffered a lot of anxiety so that when I had jobs I often had time off when according to a doctor's sicknote I was suffering from 'Anxiety States'. I was unable to keep the jobs I got. I ended up realising that Valium was causing this suffering too and not curing it. I got off the horrible drug and having done so would never touch barbiturates, LSD or Valium again. I have stuck with that decision.
