DH suffered from migraines and clusters for years, at one point landing in hospital as morphine couldn’t be administered at home. He saw specialists, tried any meds available to no avail.
We started a food diary consisting of turkey, boiled rice and banana, gradually introducing other foods. The worst culprit was dairy, especially fresh cream, we switched to Alpro soya cream and milk. He thankfully reached a point whereby whenever he recognised another one was starting, he took two nurofen which stopped a full on attack.
Now, a few years later, he occasionally has cream with no ill effect.
All the best to discovering your own cure Aussiegran ?
