My mum started 4-ap about a week ago ( I don't know the dose sorry ). She was on a trial that her neuro put her on for a week. After having 1 tab a day, they changed her to 2. Tonight, a couple of hours after the tablet, I went to visit her and she was shaking uncontrollably, she was incredibly confused and wasn't sure who I was and where she was, she kept wanting to get up and go for a walk (She has a broken leg) and was completely out of it, so much it scared me. She was also sweating and had a numb face :/ Has anyone else had any of this happen???!
