Constant migraine for over a year. Beginning of the day a pain level of 2 to 3, goes up to 8 or 9 at night. Lyrica (pregabalin) and bc for prevent. Recommend?

Stop bc. Migraines should not occur every day, and so if they do, a different diagnosis or an exacerbating factor needs to be considered. In your case, the use of bc powder every day may be causing analgesic rebound headache. This can happen when otc pain meds are taken more than twice weekly. Try minimizing otc's if you can. If still not improved, there are many other options for effective prevention.
