Although I'm not in any way medically trained I would suggest any migraine sufferer be very very wary of Tryptanes ... Mrs Image was prescribed them but they were only marginally effective had awful side effects (they seem to be related to the sort of 'chemical cosh' used in Stalinist Soviet asylums 🙂) ... she couldn't stand them for long. Another side-effects (that was helpfully avoided by her consultant!) was the possibility of hair loss (quite a common side-effect of many prescription drugs) ... what he failed to point out was that this could be total and irreversible ... you would have thought the massive effect that would have on a Woman might have made him mention it, but apparently not! ... fortunately she's a tough bird and rocks the Sci-Fi bald look and is one of those people who loves, and looks good in, just about any hat so shrugged it off.
I would say take a good look at, and rectify, whatever is causing stress in your life as step one (and, in her case, CBD oil was part of that) before hitting the heavy-duty chemicals ... especially if it's on the advice of a 'professional' who's run out of other ideas!
