Not surprising info, but definitely relevant!

I know someone who shortly was in the drug scene a couple of decades ago. They used Pervitin and said when on it you felt invulnerable, but when you came down it was horrible. They fortunately escaped from the scene after only a few months, but has said they wonder if they would still be alive if they had not gotten out.

If you're stuck on the front and unable to cycle off of Pervitin in safety the results would not be pretty.
