Hi all, Sorry, totally new to this, but very hopeful for information. I've been struggling with my weight my entire life. I am a very successful dieter- losing 45-50 pounds relatively quickly and then gaining it back just as quickly. As an aside, I was never 'thin' even after losing that sum of weight- I was just never able to continue to keep losing or even maintain that lifestyle. In the last 3 years I've had two children and since then I cannot seem to shake the weight. I lost some after my first, but was never able to get back down to pre-baby weight. During my second pregnancy, I didn't gain much weight as I was unwell, but my daughter is now one and I weigh the same as I did the day I delivered her. I cannot seem to get myself to get on a diet. I feel so incredibly discouraged and helpless. I feel like the distance I want to go is simply unattainable because its so far from where I want to be. I started considering WLS after I saw a friend of mine have great success with it. She had a vertical sleeve gastrectomy 3 years ago, but has since gained almost 50 pounds back(!) This terrifies me. If I'm a serial dieter, is this just another 'diet' in my long history? I would appreciate any feedback- so grateful for a forum to ask questions! Also, the difficulty drinking water- this may seem silly, but I think this possible consequence post surgery scares me more than anything. I drink water like its my job- I chug it- I have my whole life. Does ones ability to drink large volumes of water improve the further along you get from your surgery date- or is it small sips for life? Once again, thank you for any guidance you may be able to offer!
