I've been meaning to post a follow-up regarding my fitness situation.
Since November, I've lost over 10 lbs. I currently weigh about 172 and have gotten my body fat under 19%. People are noticing that I've lost weight, which is great, and I feel much better now that I don't need new pants!
I'm going to keep at it - just not as hard core - and try and get below 170. My blood pressure is also back into a normal/safe range, so we can consider this more or less done for now.
