Sometimes? I can't take ascorbic acid due to IBS, so I take 1000-4000 mg. of Ester C daily. Since it's a water-soluble like B-12, and there's no upper limit, it's probably not a bad idea to take it daily (amount up to what works best for you; I take more undr stress, when I'm exposed to viruses, etc.). The extra calcium in Ester C isn't bad either.

I recently had the same question about B-12 & Synthroid for my aunt (and got the same reply from mrsD). No problems that I've heard of.

Any idea why the CPAP isn't working well? There's a separate forum for that, if you'd like to go into it.

Most of the other symptoms you describe may be the Hashimoto's (from what little I've read about it - all kinds of thyroid issues in the family) but could be other things coincidental. Off the top of my head, magnesium and pantothenic acid come to mind, but that's something to investigate, decide for yourself, and talk with your doctor about. Sounds like your new PCP may have more on the ball.

Best wishes,

Doc
