Usually I take the following vitamins and supplements:

Turmeric 650mg - twice a day
Vitamin D - high strength from compound chemist - once a week
3000mg Fish Oil - once a day
A powder that contains powdered forms of about 80 things like super-foods, ginseng, macro-bioltics and other herbs, vegetables, multi-vitalims and liquorice.
Plus Iso-Whey protein as powered protein has proven to be good for Fibromyalgia.

So 5-6 tablets and two scoops of powder.

Meds listed below but that is my heavy duty IP mix. Normally I take;

Lithium 750mg - 3 tabs
Ritalin 60mg - 6 tabs
Clonazepam 1-2mg 0.5 t0 1 tabs
and rarely Olanzapine to help with sleep. - 1 tab
Oh, and Thyroxine to counteract the effect Lithium has had on my Thyroid. - 1 tab

So 11-12 med tablets.

Right now I am taking 20 - 28 meds alone each day, usually 24. I am only taking Vitamin D and Tumeric while IP though. the rest I am taking a break from.

Can you give yourself a vitamin break? Studies show it is good to do so every few months anyway unless you are seriously deficient. That would certainly take the burden off without impacting your metal health.
