My preference is to find any other way but drugs. Adverse drug effects scare me away from drugs, not to mention the cost.
Re vitamin D, in one of the recent ASW's Dr. McDougall discussed good D levels (I saw it via the internet). I don't remember exactly what he said but after hearing it I'm no longer panicked about my "severe deficiency" of 6. My fear caused me to take the prescribed megadoses (50,000 IU) for 12 weeks, read Dr. Michael Holick's book and go out of my way to get the amount of sun he suggests in his book ("The Vitamin D Solution"). I got my level up to 32, then started taking OTC pills for a couple months (and quit when I got sicker than I've ever been, and wondered if messing with D had something to do with it!). Dr. McDougall mentioned that minimum D levels are lower somewhere else (Europe or Britain?), at 20, and he said he thinks 10 might be sufficient. My sense after trying to read about D is that a lot is still unknown. Plus people in Hawaii who wrote here that they get lots of sun and their D levels are insufficient. It all didn't make much sense to me, so I decided to quit worrying, then Dr. McDougall's talk at the ASW put my mind to rest. Now, I just make it a point to get some sun. I neither sunbathe in a bathing suit nor take pills. I'm waiting until more is known before messing around with it. So, D pills are out for me. Sun is in.
