You're (seemingly) moving at a snails pace because you don't have a lot of weight to lose. So far, from my rough calculations, you have lost about a third of your excess weight in less than 2 months. That is not a snails pace.
You are what I laughingly call a Lightweight. There is a board here that will help you keep things in perspective.
The good news is as a lightweight you are more likely to obtain your goal weight. The bad news is that it will feel like an eternity until that happens.
The best I can advice is avoid the scale if the numbers are upsetting you and go by your clothes. Easier said then done but it will give you more peace of mind.
WLS 10/28/2002 Revision 7/23/2010
High Weight (2002) 240 Revision Weight (2010) 220 Current Weight 115.
Almost 4 lbs a week is not a snail's pace! For a lightweight it is a very good rate of loss.
Highest 290, Banded - 248 Lowest 139 (too thin!). Comfort zone 155-165.
Happily banded since May 2006. Regain of 28lbs 2013-14. ALL GONE!
But some has returned! Up to 175, argh! Off we go again,
Comparing your weight loss to that of others will only make you nuts. Relax. Breathe. You're LOSING instead of gaining, which is what probably would have happened had you not had the surgery. No matter the pace, you are moving in the right direction.
