Though I honestly don't know much at this point about the affects of ECA on your blood, 3 baby aspirin/day is a small dose. Blood thinning effects would be minimal, unless you are already running thin as-is.
What would concern me is the mixture of stims and forslean in HX2. If you are feeling any kind of nausea, that might explain things. For me, when I overdo it on stims, I often have the reverse reaction - become tired instead of being "cracked out". Combine all of that with some aspirin and there is a possibility of some ill-effects.
Anecdote: 10th grade biology teacher Mr. Meyers told us that if you took 100 aspirin, it would thin your blood so much that could leak out of your eye sockets. Do I believe it? I don't know. Should you try it? Hell no!!! But, to a 15 yr old, it sounded pretty cool!!! :lol:
