devboone has previously said that less than 3000 IU per day should be safe, but again this should be determined with the help of a physician, not self-selected. She said she has definitely seen toxicity in some of her patients with doses of over 5000 IU per day.

Thank you very much for the straight answer. I'd prefer not to poison myself via Vitamin D! I worry with COVID-19 other people are going to be overcompensating as well.

The easiest solution is just to be stable at a level of supplementation for a few weeks (even zero), then get a test. They're like $40 for the blood test, and then you can tell if you're in the normal range, high or low.

I believe she said "per day for years".

Yes, the assumption was that this is a daily supplement, meaning an indefinite period of time.
