Personally, I would avoid any type of mind altering drug except under a controlled environment (in a locked building supervised by doctors). I've had some family experience in this area before. Both of my brothers had colon cancer. I don't know what the doctors gave them for their treatment, but it changed their personality and made them nuts.
The first time it happened was to my autistic brother I was taking care of. I found every book in the house ripped to shreds under his bed. When I asked him about it, he freaked out and tried to run away. I tried to restrain him by grabbing his hands, but he grabbed a pack of sweet and sour sauce and smashed it into my hand and ran out the door. When I caught up to him, I took him to my Dad's house where there were more family members for reinforcements. He ended up dragging both my Dad and my brother across the floor before they could restrain him and keep him from running away. Eventually, whatever they gave him got out of his system.
The second time it happened was to my other brother. He had been missing for a couple days. We got the police involved and called the hospitals. We found him at a hospital in Poway, CA. He had escaped there once earlier that day barefoot and had been found miles away by Lowes before being brought back. He couldn't remember where he left his car, his wallet, or his insulin. He insisted on going home despite the doctors urging him to stay. We signed him out eventually and took him for food. His wallet, car key, and insulin had been in his hospital room the whole time until we signed him out (He still didn't know where his car was.) He was acting weird. He went around with a water bottle trying to "baptize" everything. He asked for some money for a snack and with the change kept dropping the coins everywhere and refused to let us pick them up. We drove him home for a night of sleep, but drove him back to the hospital the next day. After awhile, he remembered he parked his car by the fire department where he had received a ride in an ambulance. He ended up in psychiatric care on suicide watch for 2 weeks and had to sign something saying he wouldn't have any weapons (guns, knives) for 5 years.
I make sure never to let any doctor give me any type of mind altering drug with my family history. 21 years of martial arts training and a brain with a screw loose makes for a disastrous combination.
