Great job on 2 weeks! Sounds like you are doing fantastically!
I noticed the sense of smell increase, as well. I can smell a glass of red wine from 20 feet away. (and don't like it one bit)
Isn't the cognition improvement wonderful? I knit complex patterns and would often screw up and have to go back and rip out mistakes. Not any more.
You are so very lucky with your sleep. I'm not there yet.
I'm glad your aren't craving. That's half the battle, I think. Just don't become complacent!
Keep up the good work and keep posting.
