Well today I got my package in the mail to start my journey on gastric bypass and not sure what happens if I don't remember when I did things or how much I weighed when I did that do you guys think it will hurt my chances

Nope...just try your best to remember all the diets and about the time you did them and for how long. I couldn't possibly remember all that info but, I sure as heck remember 99% of all the diets I tried. I first listed every diet I tried, then how many times I tried them. Then I wrote in the length of time for the ones I remembered and how much weight I lost with each. The more recent I was able to put dates like month, year but, not for all of them. You should have a section you can write your own words right after listing all the diets so you can write in there that you can't remember all the dates/years but, that you know each one was successful or not successful, how much you'd normally lose only to gain it back...or gain it back plus. That's pretty much what I did.

Ok thanks yeah it's so hard because I really never thought I would be doing this but I hit the point the doctor said its either this or I could die or have lots more problems from my diabetes so I am trying to stick to my 60 carbs a meal now
