I feel I've improved in so many ways. I am 9 months post op so that could help a lot also. I mean there was a lot of feeling exhausted and crazy tired the first 3-4 months while my body adjusted to soo many changes. But after that my memory has improved a lot, I can pay close attention to details, and I make such better decisions. It's like after surgery I got to start all over especially with food choices so, I keep the crap out so I don't feel like crap. I eat to live not live to eat.
