I have been in it for 7-8 years and doing fine and it helps me a lot I think.
SJS always is a chance albeit very very very low on most any med not just Psych stuff , Lamictal is actually a anti seizure medication just used off label for psych.
I started on Triliptal a couple years ago and day 5 or 6 my gums started bleeding and my lip split in a 2 places so I quit it ASAP , my Pdoc said we will just watch it as there is no actual treatment other than IV’s for hydration.
I was fine and symptom free in 2 days.
Try not to do catastrophe thinking
