I'll try to keep this as brief as possible! Ive suffered from severe tension headaches & migraines nearly every day for most of my adult life. Several + years ago It got to the point where i use to take 2 Syndol tablets - the original version obviously, every night - they were the only tablets that could touch my headaches, absolute bliss. Anyway I told one GP that I was taking them every night & she barely battered an eyelash - then after eight months of daily excruciating headaches, even though I was taking the syndol, another GP wanted me off them saying they were causing the headaches.
Fast forward 8, 9 years & I'm on 2 preventative migraine tablets that I take everyday, I've recently had a 2nd bout of Botox for migraines & I'm still suffering!
Syndol was brilliant, but taking every day can cause rebound headaches as can many other OTC pain killers like paracetamol, ibuprofen. Unfortunately Codine & caffeine are worst culprits.
I've got one really bad migraine today, nothing is shifting it & I've had to take some codine - I'd love to be able to take syndol, however I suspect the missing ingredient in the new version played a huge part, the Doxylamine as a sedative/muscle relaxant probably is what gave the relief, may have a scour round for that!
