Welcome to the board. :grin:
I'm also going to chime in that abuse creates lasting problems. I know for myself it could mellow out and then wham there it would be again.
You've already received some great advice. I did want to add that I used to be scared of the medications too. But I learned thru my difficult child N that they can be invaluable in acheiving stability with bipolar. Finding the right ones at the right doses can sometimes be a challenge all by itself.
It may be time now for a re-evaluation now that he's older. Just to see where he's at and what his needs are.
