Yup, I'm a Winnipegger who went to Mexico too. I had only qualified for the MB program by 7 lbs - so if I had lost those 7 lbs in the next 2 years (approx. MB wait time) then I wouldn't have even been eligible. I couldn't bear the the thought of putting up with foot pain like I have for another 2 or 2½ years until surgery here. And we get older - I figured my body's ability to heal would be better now at my current age and weight *before* diabetes and high blood pressure hit. I had my VSG done by Dr. Aceves in Mexicali for $8750 and airfare was about $500 to San Diego. Have lost 36 lbs in 2 months, but the best part? I know there's going to be further weight loss without much effect on my daily life! I don't have to **struggle** like I did before watching what I eat and how much I eat. This is just the way it is, must eat lots of protein & healthy foods because I have to make what little food I eat count. For me, this was the right decision because now I don't have a choice. And it took me a lot of years to realize that me having a choice, made me push the boundries way too much, and hence the weight gain. I also looked at it from the financial aspect - Herbal Magic, U Weight Loss, Weigh****chers have all taken lots of money from me, so when compared to that, the self-pay surgery wasn't that outlandish.
So you need to think about why you want to lose the weight, and weigh the pros and cons. There's a couple of books you can read to help learn about the different surgeries and make your decision: Weight Loss Surgery for Dummies & The Weight Loss Surgery Workbook: Deciding on Bariatric Surgery, Preparing for the Procedure, and Changing Habits for Post-Surgery Success. I bought them at Chapters on Empress. Those books did help me in confirming that I was making an educated choice. If you feel that you want to go through with the surgery, either here or in Mexico, then look at getting a new doctor. The right doctor will put his or her personal feelings ("you're taking the easy way out") aside, and will support you in making this life-altering healthy change. They can prescribe all the anti-depressants in the world to help you deal with your unhappiness from excess weight, but really, they don't fix the problem. Losing the weight is your best bet at feeling better about yourself and being healthy (which also makes you feel good because you can do more without painful joints and cardio restrictions).
Best of luck with your decision (and finding a new supportive doctor).
