I used to take propanolol. Worked well for me for a few years until I got a dry throaty cough every 5 mins (apparently a side effect). Stopped the medication and cough went away.
Presumably as your hubby is a medical professional you've discussed such options?
I am now using this product and it appears to have stopped my migraines (monthly so I believe hormonal).

No - I do not sell this product.
I have considered whether it's a placebo but it works on babies and I never expected it to work and I'm not a strong believer in aromathoerpy or alternative therapies in general (but it's working).
If it relieves me of horrible suffereing then in one sense I don't care why/how it works (but I'm curious).
I also tried some medication (amytriptyline) which did nothing and I would have a stronger psycchological bias towards medication so I don't believe it's working as a placebo (other people also say it works).
Obviously I can't guarantee it would work for you but it might be worth a try?
Can get it from ebay/amazon but be careful which country you're buying if from if you don't want the chance of customs charges as it's not generally sold in UK only US, so ebay/amazon sellers might be from US. Several will ship to Argos.
I am really glad I tried it am I'm curious about how smells work (methol in this case).
