Does Dr pepper give anyone else really bad headaches

Now idk if it's just really crazy coincidences but for about the past 5 times I've had Dr pepper ( and I've only had it 5 times 😭 ) I've allways felt a really bad headache about 10 mintes to half an hour later ( feels like my heads split in 2 ) 😕 I was wondering if anyone else had a similar experience? If anyone knows any reasons for such an experience? Or if I'm just weird and for some reason my body denies me the necter of the gods ._. Ty for reading :)
