Maybe a 10% reduction. However, triptans work better now and the 'clear' periods are definitely more clear.
On my diary sheet, the doc has severity listed at 1-3, but in reality, if it was a scale on 1-10, I would often have headaches of 1 or 2 that I would not bother marking down.
I can also better tolerate alcohol. I still pay for it, but it's manageable.
Only side effect has been bowel movements going from 2 a day to once. (was warned about potential constipation issues)..so not really an inconvenience at all.
Would I pay for it out of my own pocket? Marginal. But it's definitely improved my quality of life.
