Opinion: Don't visit your doctor in the afternoon

It’s 3 p.m., I’ve been seeing patients for a few hours and I feel my focus fading. I need to stay sharp for those still to come, so I grab a snack and some coffee. This has become my afternoon ritual during my 20 years as a primary care doctor. Now, a new study confirms that my feared “3 o’clock fade” is real — and that it could affect patients’ health.
