Sood, sounds like you are all ready, just a matter of time passing, which I know from the recent experience is the worst. Having a type A personality, my mind worked way to hard and I too felt every muscle and ache with concern. I too made a big change in diet and exercise the 10 weeks before my surgery that helped me shed 20 lbs, I think my worry and self induced stress played a part in that too. I didn't work during those 10 weeks waiting, I tried my best to go out and enjoy being part of the things I love, watching my sons play hockey, dinning with my wife, movies, those things helped the time pass.
Now at 3.5 months post surgery life is getting back to normal, I have done a full month of cardio rehab in Jan and went back to work in Feb for 28 days. I just made arrangements to return to rehab today, because I'm off work for a couple more months with break up. I kind of miss the staff at rehab and enjoyed the interaction with others trying to rebuild life after heart surgery. So today, I have little to complain about, but lots to be grateful for.
So you got this one, be good to yourself, and keep in touch. Oh ya, my On-X is just ticking away like a fine tuned Rolex. I'm happy with that....
