Getting discouraged...

You are nearing the end of the honeymoon phase.  Everyone loses weight the first year (more or less) no matter what.  Once that phase is over though, is when the work begins. You're probably just at that transition.

Most def experienced not losing weight after some time.  I had lost a lot of my weight in the first 8 months, then for about the next year, I hit a plateau. I was so frustrated!!!!!!!!!!!!!!!!  I wasn't gaining, and def wasn't losing any weight...but my dr. had told me that I would eventually get to this stage, and it would be very frustrating. 

I just kept on doing what I was supposed to be doing with the WLS, and eventually, after that year, the weight started coming off again.

You will be ok. God is in control! Keep exercising, keep taking your vitamins, keep eating healthy, and keep a positive attitude!  This too shall pass!!!
