Migraine Pain

My wife has suffered from migraines all her adult life, and it's become easy to spot the pattern of life which brings them on. Stress piles up to the point of breaking, the release through sharing or from tears will ease the stress, and next day she will likely get a migraine. 

I, on the other hand, have only had four migraines in my life. I've yet to figure out a pattern, but this too will likely be stress related. Yesterday marked my fourth migraine and whilst not feeling especially stressed (compared to some work days), I suspect this migraine was the culmination of weeks of stressful, full on, varied workloads, and my poor brain had had enough. 

I've been considering ways to reduce my stress, and generally take better care of my body and mind, and have decided that perhaps Yoga would be a good way to keep both active and relaxed. There are plenty of good articles on the various types of yoga, and there seem to be a myriad choices of sites and apps to access this content.

The issue I'm contending with now is one of time. When would be a good time of day to conduct this exercise? Would my body appreciate doing yoga within a routine? How can I make time with busy workloads, and a customer base which can take me across half the country?

Please leave comments below, is be grateful for any suggestions.
