Mindi--
unfortunately I cannot remember what that low dose was....it was about 4-5 years ago. I'm sure I was never taking more than the lowest starting dose. I am very sensitive to medication in general. It helped my headaches, but...........
I stopped for 2 reasons:
--because I felt a little foggy on it with my short-term memory (not an area of super strength for me anyway)
---and also, I was having some difficulty with my HR spiking during workouts. It did elevate my HR by about 10-15 bpm. The dr. I was seeing thought I should stay on it, but I wasn't comfortable with being in an anaerobic range for me while doing what should have been a steady state workout. (This is just my body and one person's experience. It's not something I've heard a lot about)
This said, though, I would still try it again if my homeopathic measures I'm trying now with diet and exercise fail. I work really hard, maybe too hard, at getting triggers under control prophylactically (sp??)
But Migraines are really not livable especially when they happen frequently. There is so much time lost from life.
And there's only so much home-management a person can do without driving themselves crazy over. If I get a bad headache, now, like I did last weekend, I'm taking Imitrex or Frova (which I like a bit better, less sedating.)
So if your doc is recommending it, and you're up for trying it, I'd say give it a go. That's really the only way to know if it might work for you.
You can simultaneously work on other strategies -- observing food triggers, sleep, light, etc. and see if it helps.
Good luck!!
