Frequent Headaches?

So I typically work close to 40hrs, my jobs kinda strict so we can’t just get up and stretch whenever we need to as we’re assigned only 2, 10min breaks and a 30min lunch in a 8hr day.

I was fine when I first started, I’ve been doing this for almost a year in a few months but now whenever I wake up, I get headaches that hurt my eyes and head. It’s not a sleep issue as I sleep from around 12/1AM-10AM every night but I can’t keep calling out or leaving early due to attendance only allowing 3 days in a month but it’s affecting my metrics too (which are insane as now I’m being told if I don’t do good this month I’m forced to go into the office)

Any tips? I want to quit this job but nothings gotten back just yet or else I would but I also don’t want to keep getting myself in trouble because of these migraine/tension headaches I get like 2/3 times a week now.
