I started the 10 day, decrease to 9, 8, etc., until last day. I was on this program before; about two years, but to the best of my recollection I had no problem. This time I took the medication about 9 at night with food and I was awakened at 6 am with a headache that has turned into a full blown migraine. Because of the nature of the medication I took the other 9 today with food again, but feel just awful. I notice that "less severe" side effects do mention headache, but nothing about migraine. I never get migraines; the last one I had was about 10 or 15 years ago and it is usually caused by some external reason.
