I had my transplant in 2009. So far so good. Grateful for each and every day. Have had my bumps in the road. Hospitalized 3 times, all of my own doing. Dehydrated once, drank too much water and Gatorade, over hydrated and bit by an ant put me in the hospital with soil born disease. Afib now part of my life. Everything I have read here is all common over the years. My question is about 3 months ago I started doing 1 hitters about 5 times a week once a day. My Prograf levels were ranging about 2-4 for at least the last 2-3 years. Last blood draw a reading of 7. Stopped for 2 weeks drew blood again back to 2.8. The doctors also lowered my Prograf from 1.5mg to 0.5 for 2 weeks before the last blood draw. Pot or not. I have not started again.
