I'm glad you're improving.
I wouldn't rock the boat for at least several months after reaching a remission. Keep everything exactly the same for a while just to play it safe.
Sorry i scared you. I'm a big proponent of dispelling the fears people have over immunomodulators and biologics. They're really just yet another UC treatment and not a big leap. Fears hold us back from what's needed sometimes while UC spreads and gets more severe. Perhaps you dodged that bullet for now. Should you need them in the future then don't worry
