I had the Gastric Sleeve 10-20-14. I lost 18.5 lbs the first 3 1/2 weeks. In about the last 1 1/2 weeks I have not lost anything. A couple of days I weighed 1 lb more, and the next day was back down that lb. It does get a little discouraging. The only protein shake my doctor wants me on is the Whey protein. I have tried several of them, and in the beginning I found one I really liked. Now I am so sick of it, it is all I can do to get it down. I can barely get 1/4 cup of food down before I start to feel pain. Then, 2 hours later I am hungry again. It is difficult, when I work all day, to stop and eat every 2 hours. Last week was my first week back, and I found myself only stopping once to eat. I know I should be walking more than I do. It is difficult to walk for too long, as one day my stomach pouch will be fine, and the next day it will hurt. I struggle sitting for long periods of time (like I do at work). It causes my pouch to be sore.
You spent an entire lifetime gaining all the excess weight. It will take time for you to get rid of the excess weight; anywhere from 9 months up to 2 years before you lose all the weight you want to lose.
For me I had my procedure on 11/4/2013 and I reached my goal weight of under 200 on July 12, 2014. I had ups and downs and flats, but I followed the program. I weigh myself everyday but I don't get crazy about it either.
I now keep myself between 196 to 200. If I go over 200 I then restrict my diet. Right now with maintenance I can consume 1500 to 1800 calories. If I need to cut back (my weight is creeping up to 200) then I reduce my intake to the 1200 to 1500 calorie level.
It works.
I also posted my weight chart in my gallery for people to see that it isn't a smooth line down. It is rather choppy, but the trend was down until I reached my goal.
Here is where you can take a look at my weight chart: >>>>

Take a look.
Sit back and enjoy the journey.
As to shakes I don't understand your Doctor limiting you to just one.
I use Isopure grape drink even today to assure I get my 80 grams of protein each day.
I also use Premier shakes both Vanilla and Chocolate. Yes, you should be able to do this.
Now, I see you are in your first month so maybe that is why the Doctor is restricting you to just the whey. However, after that first month when you start soft foods, etc., etc., you should be able to enjoy differenct varieties of shakes.
Keep up the good work.
