Hope you love my inflammatory title

I am a dark-skinned individual, I do not get an adequate amount of sleep (I probably need 8 hours nightly and consistently get 6.5 to 7.75 hours). I have a bottle of 5000IU Vitamin D3 capsules. So far, I've had the flu twice in my life. Once when I was outside a lot, and partying hard, I got a sinus infection that turned into the flu.

The second time I was taking 5000IU of D3 each day. Again, I was not getting enough rest. I want to point out that 5 days into the flu, I started taking 20000IU of D3 a day, and was normal by the third or fourth day. I was also taking iodine at the time.

All that said, when I wasn't taking D3, I wasn't getting sick. Like not so much as a cold. That's why I am starting this thread. I'm hoping to hear from the other D3 'experimenters.'

A note on sleep. I am not mentioning this so all the supporters can just say "well he wasn't getting enough rest" which is obvious and clearly a common thread here. The important thing I want to mention is that I personally observed the combination before an illness.

My third story. I started to get 'gung ho' about D3 again earlier this year, and took probably 20000IU a day for a week, then started back on taking 5000IU a day after that, but I clearly noticed I started getting a sore throat, a few days in. It would happen during the day and clear up by the evening (I took my D3 in the morning) but after some time wasn't clearing up in the evenings.

I started sneezing and coughing and my cough got worse and worse -- the infection moved from my nose and throat into my lungs, and I thought I was going to get the flu.

Again, I was not getting adequate sleep. This time I suspected the D3, so I stopped taking it. A few days passed and I kept getting worse, so I took a day off from work and slept in. By the next evening I was 100%. So in every instance here, I was not sleeping as much as I should have. But the common thread in every instance was high D3, and inadequate sleep.

Probably either what a proponent of it would call normal...but I have to really question this, because I got sick at this time...and I could have instead, not gotten sick at all. I find that pretty interesting.

I'd like to get your opinions on this.
