Hey, congrats on your wedding! I have not had the surgery, but I did take a peek at your FitDay. I think the ladies here who have had wls would tell you that after, you need to make sure you eat some protein w/every meal, and so I would suggest you might look into eating more protein now, which might make you feel better and more energetic. You get very little protein now but lots of carbs and fat. If you could add in some more lean protein and make your pie chart look more like 40% protein, 40% carbs, 20% fat (or even close to that), I think you would start feeling better after 2-3 days. Right now it looks like you are about 50 carbs, 30-40 fat and 10-20 protein, and some days you get very little food. You could eat a lot more volume of food if it was a different kind of food. Things like lean deli ham, deli turkey slices, yogurt, hard boiled eggs, oatmeal, cheese. Since these are the changes you would have to make in your post surgery diet, you might want to give them a trial run now to see if it gives you more "good" days where you feel better.
Good Luck! Lots of people here will post food suggestions if you want them too.
