So should i take vitamins/birth control at a different time then my sinthroid?
If the vitamins contain iron or calcium, they should be taken at least 4 hours apart from thyroid medicine. I have not seen proof that it should be taken well apart from estrogen-containing birth control, but to be safe, it should be.
Ideally, thyroid med should be taken by itself on an empty stomach, one hour before eating. If you can manage to do that, you will be getting the maximum benefit from the med. If you can't manage it, there may be other ways to work around it if you're creative and consistent.
Now then.... You mention fibromyalgia. Have you been told you have it? Fibromyalgia is a common diagnosis for what is in reality under-treated hypoT. You seem to be clearly undertreated. The "fibro" may actually be that.
Wait and see what happens with this increase in Synthroid. I hope you have been scheduled for a follow-up visit and blood testing in a few weeks to see if your TSH is coming down.
Meanwhile, read Thyroid for Dummies
which will help you understand the tests and treatment. If you understand your condition, you'll hopefully be able to understand when you aren't getting the best treatment you could be.
Edit to say ~ When you call the office for your results, don't just accept them over the phone. Always ask for a photocopy to be sent to you. It's your right by law to have them. You can post the results/ranges here for help in interpretating them.
