That's awesome man - nothing better than pushing yourself past a wall, whether self-imposed or externally imposed. Congrats!
Regarding the paleo diet - it's actually really easy (at least for me) to stick to (except the Bourbon, damnit). The first few days I was craving some bread and a glass of milk, just cuz of old habits. But after a few days I stopped really even considering them as food. My mood swings have disappeared, I never have big hunger pangs or those "fatigued" moments you get, like post lunch at work anymore. And I am sleeping a ton better.
Workout-wise I seem to be doing okay but since I am currently in a calorie deficit I haven't knocked it out of the park every workout. I am still playing with the numbers to find the optimal balance. I'd really like to lose another 20 pounds and get down to 8-10% body fat.
Mostly I just want to be able to keep up with my wife.
