yeah, depending on how hard u want to roll... what sort of environment would u be in? normally i'd advise to just take the whole thing but u'd still probably feel effects if u dropped half, but they'd be minimal (depending on pill quality)
yes it is possible. SWIM finds taking half a pill pointless and you probably will too. But if you insist on it then you should crush it up into a fine powder (use a knife to break it up then get a credit card and rub on the peices hard and it will make it into a good powder, repeat if neccesary). Then you should cut the powder into 2 groups and parachute one, and the other half later if you want to.
dont even bother with half a pill, chances are it wont be great quality and u will feel little to nothing, waste of cash in my opinion.
I only did it once, it was half a pill. I felt quite happy ... content ... chatty but not on any type of trip.
had half at my year ten formal dinner and found out it was a speedy one, but still had an extra good time i could feel it but not overly, it wasnt hard to act sober but i could let mself act high if i wanted to? hemoglobin?
