weaning labetalol

has anyone ever been on labetalol for years and then finally been weaned off? Lemme hear your success stories! I’ve been on 200mg 2x daily and now my OB says I can just take 1 pill a day and see where that lands me at, so that means 200mg total daily. I’m researching online that 400mg total is a very small dosage compared to what they normally prescribe.
