I was on it for a bit over 3 years. It was much needed at the time, I was able to find stability. Any increase gave me GI problems for a week or so, But it resolved.

I choose to stop taking it due to a few reasons, I went toxic once, I was worried about long term use when it comes to Thyroid and kidney function.

Maybe at some point I will need to go back on it, Or maybe I won't. I will cross that bridge when it happens.
