Any idea what drug this might be from? Paranoia, agitation and even extreme anger. Some insomnia. Delusional thoughts. Later on skin irritations. They surface as hard bumps. If you pick at the bump it turns into a sore that doesn't seem to want to heal. Something in the center. If picked it lasts months. They hurt and make a scar once dissipated. If the bump is left alone eventually they go, but it takes a very long time. Possibly makes the eyesight blurry. Deep depression. The skin also itches when those bumps surface.
