Centrum is probably not enough. These are the bare minimum of vitamins helpful for those that are not sick. I find if I only take 500mg of Vit. C I am deficient in it and do not feel any benefit. I too have about that amount of fillings and have the same symptoms you have.
You can get all the filling removed at once. Some dentist will only do a few at a time. However, you really can't begin to detox until they are all gone. Do not take Lipoic acid until all your fillings are removed. Huggins protocol is good. Another view is www.iaomt.org
A basic supplement list to do before removal might look like this:
Buffered Vitamin C: 1/2 -2 grams four times a day
B complex: (a b-25 or b-50) four times a day
zinc: 50-100mg divided into four doses taken throughout the day
Magnesium: 500-1000mg in divided doses (four per day)
Milk Thistle extract: 1/4-1 capsule per dose, taken four times a day (20-80 mg a day total)
Vitamin E: 500 IU
Mixed carotenes, lycopenes
Flax and/or Borage/or Fish Oils(Essential Fatty acids)
: 1-3 Tbsp per day
Selenium: 200 mcg as selenomethionine divided into four doses each day
Chromium Picolinate: 200 mcg with every meal
Molybendum: aprox. 1000 mcg a day divided into four doses
NO copper
Vitamin A: 5x the RDA divided into 3-4 doses per day

Some of these may seem high but they would be divided into four separate doses taken throughout the day. This is because mercury toxic people do not absorb nutrients very well and water soluable vitamins must be take more than once a day. You can find multivitamins of good quality that will meet close to these amounts. Some things you will have to take as a separate supplement. After your fillings are out you would continue the supplements but could begin to remove mercury using Lipoic Acid. Frequent low dosing works better. (The best place to find info in this is a book called Amalgam Illness by Dr. Andrew Cutler)
Oh and taking Algin is helpful to absorb the daily exposure you get while the filling are still in. Thus a good point for having them all removed at once.
