so, it's consistent - it takes the aspirin about an hour and a half to take effect, and over two hours to really work. when the aspirin is working, i can feel the headache as a dull stab in the back of my sinuses, if that makes sense, but it doesn't overtake me - it allows me to function. the aspirin then works in keeping the headache manageable for roughly 20 hours, before it gets debilitating again.

the last several times i took tylenol, it did not work at all.

i am neither a chemist nor a doctor, but the evidence in front of me suggests that the aspirin is functioning as an anti-coagulant, rather than as an anti-inflammatory drug. the reasons for this are due to the ineffectiveness of tylenol and both the delay in aspirin working, and the length of time it lasts for.

i am going to bring myself back to the hospital over night under the premises of concerns about clotting, and hope they can advise on immediate steps in a way that avoids a catscan.

i am probably not at risk for a heart attack, but i may be at risk for a stroke. and, i may have actually had a stroke on that night, due to the interaction of nicotine with estrogen.
