Thanks all, sorry for the delayed response, I have spent most of the day in bed or sorting my children out. I really appreciated the replies, it's always good to hear you're not alone.
Vision is ok, I have contact lenses and regular check ups, I have ordered a pair of blue light glasses to try as I spend quite a lot of time on a computer - thought it was worth a try.
Trigger wise my main triggers are alcohol, caffeine and sugar. I'm pretty good with alcohol and caffeine but do know sugars are creeping in as I've been eating more convenience food.
I think the biggest problem for me is stress and I hold my tension in my neck, head and jaw. I have often wondered if Botox would be helpful. I sleep badly and this is also worse when I'm stressed and poor sleep is a definite trigger.
I am really hoping it's not medication overuse as the thought of stopping everything terrifies me. At present I am limiting to 2 paracetamol a day and 1 sumatriptan every other day, although I haven't had anything today as I was starting to wonder if this is the case.
I have tried the aspirin that was suggested about two hours ago and do feel a bit better, I've managed to wash my hair which I hate doing with a headache and think I might make it to my mother in laws later for our weekly roast! I had been planning to stay in bed!!
I've tried a lot of preventative meds pisotifen, amitryptaline, noratryptaline and propanalol, they all seem to work at first but after a year when my meds are reviewed it's always noted that I'm still reporting the same number of headaches and taking the same amount of sumatriptan so it's not worth changing. I will call the GP tomorrow though and see if anything else is available.
Thanks again, I feel my husbands tolerance of this is waning and it's been good to think it all through with others
