I have sinus problems too, had sinus surgery last year. I started pulling yesterday (first time) with a minor sinus headache. Stayed the same. I drank beer all day at a baseball game which tends to lead to a migraine (at which point today i would take a migraine pill to alleviate it). This morning i woke up with about the same level headeache i had yesterday. So i pulled again this morning, by mid afternoon, headache completely gone, and i feel pretty great considering i drank all day the day before. That never happens for me anymore. My sinus's have been draining all day. I hope yours start to feel better too.
