I had my license suspended due to my lactulose medication. It was Nov 2016 and I had a few major HE episodes so it was deemed that I should not be on the road. I didn't have it renewed until the end of Aug this year, 2019, when they felt I was ready to get behind the wheel again. That was almost 9 months post transplant. It was tremendously inconvenient but they were right. Any hint of dizziness, loss of concentration or misjudgment and I would have had an accident. I'm glad now as I feel much safer with my driving.
