What is the best time of day to take aspirin for blood thinning?
I've been on an aspirin regimen for years. I usually take it at night so that it doesn't bother my stomach in the morning. Is this the most effective time to take it as a blood thinner?

There was a presentation from a study from 2013 that looked at this question in the context of heart attack prevention and found: "There is a body of research that suggests the majority of heart attacks occur in the morning. So taking aspirin before bedtime may be the better bet as it allows time for the medication to thin the blood, which reduces the risk of heart attack." BUT the study was never published in a peer review journal that I remember and these researchers did not directly measure whether aspirin taken at bedtime reduced heart attacks. They measured whether it reduced 2 risk factors for heart attacks – blood pressure and platelet activity.
People advised to take aspirin by their doctors should take aspirin at whatever time of day they find easiest.
