Cblack, do you have any symptoms that may not seem to be related to the symptoms you're talking about - the fatigue and loss of energy? Diarrhea? Rashes? Are you also saying you have 'brain fog?' Have you been checked for celiac disease?
Have you had your thyroid levels checked?
We do have a "gallbladder" forum now, so be sure to stop by there. But I can tell you that if you will take a complex multivitamin and mineral supplement with IRON in it a couple times a week, and eat steaks when you can, you just might notice a return of normal focus and strength. When the blood cell counts get too low, usually after an operation like the one you had six months ago, iron levels can drop. You notice this more after you eat, because all the blood rushes to the stomach to digest. When you're in department stores and get that sensation, try some deep breathing, but my guess is your eyes are also affected by perhaps low Vitamin A levels, too, which the supplement should help that, as do carrots and sweet potatoes. But see what the gallbladder people say about proper nutrition after its removal.
