Vitamin intake

I would like some advice on my vitamin intake and if it's ok to take all the vitamins I take daily. I am 57 yrs. old and have Fibromyalgia/Chronic fatigue syndrome. I am on daily medications for underactive thyroid (Eltroxin), high blood pressure (Lisinopryl), and estrogen (Premarin). I have tried numerous meds for my FMS but nothing has helped so far. I am taking the following vitamins daily:
A Multi-vitamin, 1000 mg.Vitamin C, 1000 IU Vitamin D, Calcium Citrate consisting of 200 IU of calcium and 315mg. of Vitamin D, and 1000mg.Omega 3 Fish Oil, 2-3 times/day, and 1000mg Echinacea.

Is there a problem taking these daily and should I take anything else?  Because of my FMS I'm not as active as I should be that's why I try to take various supplemants. There is a natural product for FMS called Fibrosense I am considering trying now but will take any vitamins that might help as well.
Thank you.

An intake of Vitamin D 400 IU is sufficient for your age. You should not go over that amount in supplementation. 2000 IU is the tolerable upper intake level for adults; however, you can be at risk for toxicity (weak muscles, weak bones, excessive bleeding, and kidney stones) if you also consume large amounts of fortified milk / dairy products and fish. Vitamin D is available through our foods - Fortified milk, breakfast cereals, egg yolks, fatty fish, fish oils, and the sun. Sit at a window with the sun shining in for about 1/2 hour (few times a week) and that will help you get enough Vitamin D. Suggest you find another calcium or a multivitamin supplement with less Vitamin D (or none at all) to help lower the amount of supplementation of Vitamin D. Suggest decreasing the amount of supplementation of the other vitamins and replacing them from your food sources.
