I will interject here that you likely would want to wait at least 2 weeks after starting the D3 Regimen before tapering off any. Having your D checked also would provide vital information and you are probably in the best position to try for that, being a doctor. If it is above 80ng/ml or a good nmol/L reading, then you can taper down. The values for each are different as I am sure that you know. But just compare the two to determine your levels.
On the Verap, I removed one pill per week from the time when I least expected a hit. Meaning, I removed the morning one first as I was nocturnal. The nightly dose went last.
If you are nocturnal, then I strongly suggest a cup of coffee or an energy drink late in the day. It has helped me a LOT with the standard 8pm hit as it does prevent it coming.
