If I can catch my headache/migraine early, the following regimen works for me. I take Feverfew (standardized to .7% Parthenolide), White Willow and Magnesium (Citrate) with lots of water. Sometimes I make few cups of tea with Feverfew and White Willow. If it's early in a day, I add a strong cup of organic black tea.
Perform either with your head on the floor, or with your torso and head supported on a bolster positioned between your thighs. The bolster's long axis should be parallel to your torso. (Total time 3 to 5 minutes.)
Support your head either on a bolster laid across your extended leg, or, if you're less flexible, on the front edge of a padded chair seat. Hold each side for 1 to 3 minutes; total time 2 to 6 minutes.
Support your head on a bolster or block. (Total time 1 to 2 minutes.)
Place your head and crossed forearms supported on a padded chair seat. (Total time 1 to 3 minutes.)
Support the torso on a rolled blanket underneath and parallel to your spine. (Total time 3 to 5 minutes.)
Support the torso on a bolster, and shoulders and head resting lightly on the floor. (Total time 3 to 5 minutes.)
Let the pelvis be support either on a bolster or rolled blanket. (Total time 3 to 5 minutes.) To avoid any possibility of straining your back when exiting, be sure not to twist off the support. Either 1) slide off the support first before turning to your side, or 2) bend your knees, press your feet against the wall, and with an inhalation lift your pelvis off the support; then slide the support off to one side, lower your pelvis to the floor, and turn onto your side.
Take normal inhalations but lengthen the exhalations as much as is comfortable for you. If you normally take 5 counts on an exhalation, extend it to 7 or 8 counts if possible. At the end of the first 10 or so exhalations, pause for 2 to 5 seconds before drawing the next inhalation. (Total time 10 to 15 minutes.)
