Can anyone relate to being a headachey person and what do you do to deal with it ?

I am also a very headachey person and it sucks. I have been diagnosed with chronic migraine even though most days my headaches are just headaches and not full blown migraine.
i Wish I could tell you xyz has worked for me but I’m still trying to conquer them myself. Best thing I did was get referred to a headache specialist neurologist though. You may be in a trap of rebound headache/medication overuse headache, I certainly was. It’s really hard but might be worth giving up all painkillers for 3 months. You don’t have to do that alone, a headache specialist can prescribe a short course of steroids to help break the pain cycle.
Other non painkiller option that helps me are tiger balm on forehead temples and neck and drinking electrolyte drinks when I feel a headache brewing.

I get awful headaches that can last for a few days. Similar to you I've identified triggers

not getting enough sleep
Some smells - a couple of different perfumes
being dehydrated
alcohol
Sitting too long/Not moving enough

Paracetamol and ibuprofen don't seem to do much for me. But (don't laugh) I've found that a bowl of mashed potatoes really does help! I don't know if there's something in the potatoes that I'm deficient in, or some weird placebo effect, but they are a pain killing magical superfood!

I had really terrible headaches on and off for about 20 years. About 19 years ago a very nice lady GP said that they found out by accident that antidepressants help with headaches. I took one Amitriptyline and never had another headache. Kept the packet with the other 19 pills still in a drawer.

I get headaches regularly. Anything a bit 'off' gives me one, so lack of sleep, a bit dehydrated, too noisy. At the moment a lot of mine are linked to neck/shoulder pain, so I'm working on strengthening my neck/shoulder muscles.

I've considered a shakti mat so interesting it has helped you @Lmnop22

Yes, I used to get lots of headaches when I worked full time in a busy stressful office job.

I’m introverted and suspect I am ASD. I am in a position now where I am very fortunate that I can limit time in social situations. I also get lots of time to decompress. I feel much much better and only get the odd headache.

I was PLAGUED by headaches and migraines before I was diagnosed b12 and iron deficient. Since I have started b12 injections and started taking a regular iron tablet my headaches are (almost) gone. So I’d recommend a blood test and make sure it includes ferritin (iron stores) and b12. And google the results as they’ll say ferritin is fine if above 15, but really you can be symptomatic if under 100!! And b12 they’ll likely say is fine if above 200, but again, you can be symptomatic if below 300 xx

I had some cranio sacral therapy when mine were at their worst. I was a sceptic but things definitely improved.

I have been plagued by headaches and migraines for years, my triggers are using anything with screen for too long, alcohol, reading in cars, not enough sleep. The GP said it was rebound headaches from too many painkillers, but eventually I got a prescription for rizatriptan, nightly nortriptyline and beta blockers. I take 2 x 200g into and 2 paracetamol extra. If required I take a 2nd set or ibro and para with a rizatriptan.
The point of my post is to say there is medication for you.
Mine are connected to my eyes, so make sure your glasses are spot on prescription wise. Even if prescription is small try glasses as my brain can't manage a small difference between eyes.
Consider glasses just for reading.
Ask to see a neurologist. Or a headache clinic if there is one near.
You could look up the migraine trust
Try a physio that specializes in headaches, I have a relative that has her neck treated by a physio, with good results.
Hope you can find something to help, headaches are miserable.

I’m same and quite prone to headaches and I bought a shakti mat which I lie on and if I use it on my upper back and neck I find that eases a headache for me and using it regularly reduces frequency of headaches.
