I'm 34 and had my RNY on March 17th, 2014. I was 242 lb pre-op and I am now 188 lb. I have not lost weight as quickly as others but, on the plus side, that means the skin has more time to recover and you get less saggy skin. I'm not married but I do have a boyfriend.
I haven't been as good with exercise, though I am currently in the alpha phase of the T25 workout and looking forward to seeing results from that! I also go walking about three times per week, but haven't done much in terms of strength training though I'm incorporating that as well.
In terms of regret, the feeling is more for specific moments. Our brains are trained to eat and drink huge quantities and the surgery does not change those. As your body changes and you can do new things (like cross your legs!) you'll realize why those sacrifices are worth it an welcomed!
I look forward to getting to my goal weight (135 lb) and seeing all I'll be able to do then. In the meantime, I'm definitely planning ahead! I signing up for a tough mudder race in July 2015 and already buying clothes for next summer (size medium!).
The picture below is my current before and after. My hair was really long pre surgery and I cut it off to donate to locks of love.
