Yeah, I wouldn't go with 125 rolls either.
The five dice also allows for easier variation off the average.
Sorry about the cold.
One D3, Zinc and Selenium daily will bolster your immune system. 1 D3, period. Up to 2 Zinc, when you have symptoms, and up to 6 Seleniums split throughout the day at meal time (only bad symptoms). 1 Se daily for prevention, 2 if a coworker has symptoms and 3 at onset of symptoms, 1 with each meal. more, up to six if symptoms get worse.
Note that this does not preclude a doctor if you see no improvement in the same amount of time you'd normally procrastinate before making that call.
My son was notorious for getting the semi-annual crud, and being out for at least a week - needing antibiotics to finally beat it off.
We got him the above, and he got well over the weekend. His boss was amazed. He hasn't needed the antibiotics to get over a sinus infection for two years.
