I find propranalol OK, but only OK. I do still get migraines but they're not as bad or as frequent. Before it was prescribed I had Naramig which was really good but you can only use it for so long and I'd been using it for over 5 years (maybe 10). It also couldn't be taken every time.
I was getting the aura all the time, literally. It would be there for 15mins and then a 10 min break, then it would be back again. I was always confused, not really with it, had visual hallucinations, loss of balance etc etc etc. I still get the auras and aome confusion and sickness about twice a week with propranalol.
I'm excited that in a couple of years they may be prescribing me a real preventative.
