Good luck & keep updating your progress. I'm not doing Paleo, but Atkins which is similar. I have nut and fruit allergies so I figured without those, the diets/lifestyles are quite similar.
When I dropped the carbs, processed foods, diet soda, sugars, etc, it was difficult. I felt crummy for about 5 days. After that, I felt fantastic! I had loads of energy. That surprised me the most. In the first 14 days I lost 12 lbs. In 5 months I lost 56 lbs. I had to quit, however, due to a wonky gallbladder. But now that I've had my surgery I'm back on this way of eating.
I hope you enjoy your new lifestyle!
