Congrats! It's a wonderful feeling to ring the bell! As a couple of others have said. Hang on... the ride isn't over! The next few weeks post Tx are as brutal or worse than the treatment. I'm 10 weeks post and while I'm markedly better, I'm still a hurtin' puppy.
It's more vital that you continue to hydrate and nourish yourself post Tx. You should begin to turn the corner 2-3 weeks from now.
Positive thoughts and prayers,
