Yup. I take one every morning, along with a handful of prescription meds and some vitamins, and carry more along, in case of the big one. Or a simple headache. Then do not bother my stomach at all, nor do the 800mg motrin I take on a pretty regular basis for my bum back. A co-worker got chest pains at the office one night, his partner had him pop an aspirin then ran him over to the hospital...minor heartattack, no damage, thanks, according to the dr, to the aspirin...
