Winter in Canada - bigger than Lesnar, longer than Corey Hill's leg rehab, stronger than Emevas, but I'm still going to make it my bitch!

Winter pisses me off.
I use my rage to full my heat.
Especially when I reach the end of my driveway shoveling and the fucking plow comes and dumps a ton of compacted snow at the end.

Eight subjects received 100,000 I.U. of vitamin D and seven subjects received phototherapy. At the onset of treatment and after 1 month of therapy subjects were administered the Hamilton Depression scale, the SIGH-SAD, and the SAD-8 depression scale. All subjects receiving vitamin D improved in all outcome measures. The phototherapy group showed no significant change in depression scale measures.
Regarding the dangers of megadosing, here's Wikipedia:
Maximum endogenous production with full body exposure to sunlight is 250 µg (10,000 IU) per day. [ ... ] dosages up to 250 micrograms (10,000 IU) /day in healthy adults are believed to be safe. [ ... ] all known cases of vitamin D toxicity with hypercalcemia have involved intake of or over 1,000 micrograms (40,000 IU)/day.

Take your multi and get your UV.
It's for the long term, not the overnight.

If there is a generally-accepted protocol for administering therapeutic/pharmacological doses of Vitamin C post-operation, I am unaware of it.
Intravenous administration is especially troublesome for two reasons:
1) It circumvents the body's natural mechanism for regulating Vitamin C intake (diarrhea)
2) My understanding is that a single administration of Vitamin C will only have a transient effect on serum levels (see this graph). There are time-released vitamin C tablets available, but causing a prolonged increase in serum levels via IV would require your husband to haul an IV tree around all day.

Re: Jack Skellington's post... agreed that Vitamin D is a reasonable intervention for SAD. The theory makes a lot of sense, and if nothing else, it's unlikely to do any harm. Oral Vitamin D sources/supplements are cheap, the body can readily inactivate excess amounts, and as you noted, the RDI is probably too low (given that I drink between two and four litres of fortified milk a day, I'm getting somewhere around your order of magnitude extra).
I'm not sure how good the first study is - it's not blinded, and it's not controlled as tightly as I'd like (the phototherapy group may function as a rudimentary control, but that depends on the details of their treatment). I'm puzzling over what this means...
Vitamin D status improved in both groups (74% vitamin D group, p < 0.005 and 36% phototherapy group, p < 0.01).

Don't forget to get some quality outdoors time in, even if you can only do it on the weekend. My wife was suffering the effects of SAD and the most effective thing for her was outdoor physical activity during the day. She's fine all winter as long as she takes her multi and I drag her out of the house once a week to go snowshoeing or cross country skiing.

As for the first paper, a quick tour of PubMed will turn up much other work. The comment paper that got me on the D train was sent around by an MD/Phd friend earlier this year: Cod Liver Oil, Vitamin A Toxicity, Frequent Respiratory Infections, and the Vitamin D Deficiency Epidemic. It recommends that healthy children take 1,000 IU/day of vitamin D for every 25 pounds of body weight. In some cases this is more than ten times current recommendations.“Most people do not do, but take refuge in theory and talk, thinking that they will become good in this way” -- Aristotle, Nicomachean Ethics, II.4

The bit about hypervitaminosis A masking vitamin D is especially bothersome... I've been trying to avoid overdosing on retinol, but it's hard when preformed retinol is added to milk and present in multivitamins. I don't see why they don't just stick with beta carotene in the multis - all the benefits without the risks.
