Dr. visit yesterday, question about vitamins

Went to my family practice physician yesterday still feeling yucky and found out I have another ear infection and sinus infection.  They cut my atenolol in half to 25mg/day because I've been experiencing orthostatic hypotension and my heart rate is too low, 54.  She took away my Bumex which means I'll probably gain about 5-6 lbs in fluid before I level out.  I got her to increase my Zoloft so that I won't be so bummed out about that, lol.  She also recommended I start taking 2000iu of Vitamin D a day and 1000mg of Vitamin C a day along with my Calcium Citrate and multivitamin.  What does everyone else take?  Oh, she also gave me a B-12 shot and this morning I feel really energetic.  Just too sick to go for too long.  It's driving me crazy since we are trying to finish up the remodel on the living room before Christmas.  I am dying to put up the tree but can't until we are done.  Our Christmas present is going to be some new furniture pieces for the room when it's done.

Daily
1 prescription bariatric multi-vitamin
2 super B-complex vitamins
3 - 6 sublingual B-12 daily (usually 3 in the morning & another 3 sometime later in the day if I think about it)
4 chewable vitamin C (2 in the morning, 2 at night)
8 citracal plus (2 tablets after each of my 4 meals for a total of 8 pills per day)
1 precription iron (Tandem - usually in the middle of the night or right before I go to bed - by itself)

Weekly
1 prescription vitamin D

Theoretically, if you were doing Vit B shots, would you then eliminate your daily B intake?  I called Addie today and got her to call in the shots for me in hopes I could drop the pills, but if it's better to just keep 'em up, then I'll do that.

If I was doing Vit B shots, I wouldn't take the pills also.  (I'd make sure that the shots were B-Complex shots though, not just B-12 with a few accompanying Bs.)
