Im sorry youre having these problems and although I havent had the surgery, I have done some research about it so I will chime in until someone more experienced can give their input....
First of all, have you spoken to your surgeon? I see where you mentioned seing other specialists but having now more experience with this surgery, your own surgeon might have some data for you or at least be able to make some recommendations. If that doesnt work, I wouldnt hesitate to try to contact Dr Rutledges office and see if he can make any recommendations just based on your symptoms, All they can do is say no but its worth a try.
Secondly, I would recommend posting your most recent lab results and a list of the vitamins you take (including mg and brand etc) as there are many people here that can look at your results and tell you if theres something you might not be seeing. ALSO I noticed that the vitamins you seem to be deficient in (Iron B12 and D) are also the 3 big ones that you cant get from a run of the mill tablet so be certain to post what type of Iron, B12 and D you are taking so we can help you make sure youre taking the right kind you also need to post WHEN you are taking those vitamins because lets say youre taking your iron and your calcium at the same time, well that would be your first problem, even if youre taking your iron say in the morning with cottage cheese (which contains calcium), thats going to cause you to not absorb the iron so its not just about what youre taking but WHEN and WHAT WITH.
Also, are you getting enough salt? I remember from watching some youtube videos about the mini gastric bypass and salt that some people were having some of the symptoms you describe dry mouth, dizzyness, joint pain with a low salt intake. I would at least look at those videos and see if that might be a simple thing to try. The salt issue isnt just for newly post ops....Invest 8 min watching this (there are plenty of salt videos in dr rutledges files on youtube but this one mentions how its a long term concern and at least it might resolve a small part of the problem.

Im sure if you
post your most recent labs, vitamin regimen (what, how much and when) and a sample of what youre eating in a given day (what, how much and which meals you are taking with which vitamins) and a list of any other meds youre taking and when, you will get lots of direction from this group. At least it will be a good place to start and might even solve your issues.
Best of luck to you!
