B12
Okay first things first I am PRE OP! I have a horrible time keeping my D levels up, I just finished another 8 weeks with the 50,000 1x a week and now I've got myself on 5,000 a day. But that keeps my energy level at about bare minimum. I thought I might try B12 to see how it did and I bought some sublingual at the commissary. But I have no idea how often I'm supposed to take it. Is it once a day, twice a day, or once a week? Any help would be appreciated.

Have you had your labs drawn? I'd see where your values are before blindly supplementing.
I don't think I've ever read that Vit D impacts energy level? But maybe it does and I just don't remember.
Have you had your thyroid tested? I was having an awful time with fatigue, and my PCP found that my thyroid was borderline low. He put me on a low dose of synthroid and the difference was night and day. Many Dr's won't even treat at the level mine was at, but it made a big difference for me. And there is research supporting the guidelines my Dr used - it is just fairly new, that's all.
Another thing that has a big impact on energy level - being adequately hydrated. That's a minimum of 64 oz, and some people need even more.
Sorry for the unsolicited advice, but thought I'd offer it in case it helps!

I'm confused regarding the B12. I see from the posts that everyone is taking B12 daily. Is that correct? I give myself B12 shots monthly which my doctor prescribed. I'm taking 0.1 milliliter monthly. Should my dosage be higher and more frequent?
I am 5 weeks out and I am extremely tired all the time as if I am a few days out. I am only able to walk outside or on the treadmill for about 45 minutes to 1 hour and I am winded and very exhausted. Is this normal? Any suggestions?

Here's some info I lifted from the NIH site on B12 for you. It may help. With the removal of a large portion of our stomachs the B12 is not readily absorbed - thus the sublingual vitamin.
Vitamin B12 is a water-soluble vitamin that is naturally present in some foods, added to others, and available as a dietary supplement and a prescription medication. Vitamin B12 exists in several forms and contains the mineral cobalt [1-4], so compounds with vitamin B12 activity are collectively called "cobalamins". Methylcobalamin and 5-deoxyadenosylcobalamin are the forms of vitamin B12 that are active in human metabolism [5].
Vitamin B12 is required for proper red blood cell formation, neurological function, and DNA synthesis [1-5]. Vitamin B12 functions as a cofactor for methionine synthase and L-methylmalonyl-CoA mutase. Methionine synthase catalyzes the conversion of homocysteine to methionine [5,6]. Methionine is required for the formation of S-adenosylmethionine, a universal methyl donor for almost 100 different substrates, including DNA, RNA, hormones, proteins, and lipids. L-methylmalonyl-CoA mutase converts L-methylmalonyl-CoA to succinyl-CoA in the degradation of propionate [3,5,6], an essential biochemical reaction in fat and protein metabolism. Succinyl-CoA is also required for hemoglobin synthesis.
Individuals who have had gastrointestinal surgery
Surgical procedures in the gastrointestinal tract, such as weight loss surgery or surgery to remove all or part of the stomach, often result in a loss of cells that secrete hydrochloric acid and intrinsic factor [5,39,40]. This reduces the amount of vitamin B12, particularly food-bound vitamin B12 [41], that the body releases and absorbs. Surgical removal of the distal ileum also can result in the inability to absorb vitamin B12. Individuals undergoing these surgical procedures should be monitored preoperatively and postoperatively for several nutrient deficiencies, including vitamin B12 deficiency [42].

Hi,
I would get your B12 levels checked before taking B12 vitamin. I was just at my doctors and found out my vitamin B12 level is too high (he said it does not harm you to have too high of a vit B12 level)
I was supplementing with 2500 sublingual about 4 times a week post surgery.
I guess i didn't need that much.
I have never heard about Vitamin D and energy levels either. Doesn't mean it isn't true of course, maybe your doc knows about some new Vit d research that links it to energy levels...
