I had lipo on my upper and lower abs, flanks and axilla two months ago. It was definitely worth it for me, but every person's experience is different. In my case, I was already a fit person of a healthy weight and I was using it to contour a couple of stubborn areas. I suspect lipo is most successful when used this way.
My expectations were realistic. While I look much better than before, I am still not perfect. I was also not expecting significant weight loss from the procedure (if you're looking to lose a lot of body weight, you still need to do that on your own).
I was also very proactive in my recovery. I was religious with water, massage and compression garments. I also do not smoke. I believe these things contributed significantly to my success.
