Remains to be seen if I make a comeback.....but I had a heart transplant 2 months ago at age 41. I am gradually building up my activity level and the lengths of my walks with hopes of getting back to running, cycling, etc. I was not pretty darned fit before, although at this point in my life not competitive. During this experience I have been encouraged by many stories of heart transplant recipients who have recovered to run again, do triathlons, long distance cycling, and endurance swimming. A previous post mentioned forgetting where you were before, only the post cancer times count from now on, you are truly born again,given a second chance to get different times, maybe not better. I hope to recover well enough to enjoy my 'second life' even if running becomes jogging. I agree about seroquel, it made me actually hallucinate, I couldn't tell if I was sleeping/dreaming or awake! I found remeron to be the one for me. Hang in there, be patient with yourself, and best of health to you.
