FWIW, I'm using propanolol. I started with 20mg twice daily and I was too drowsy but I'm on a lot of meds that cause drowsiness so it doesn't take much to make it worse. I was still getting migraines, but not too often. I did have to reduce my dose to 10mg twice daily and I feel as though I'm on the verge of getting a MH a lot of the time and I'm still getting them, but the drowsiness for me is a little more manageable. Its a fine line between the right dose and too much, for me, but the drug is helping control the MH's so I'm staying on it. I'm new to MH so my experience is limited here. I do hope it helps you.

Take care, ee
