This most likely explains why i felt sedation! The oil is nearly as clear as the solvent, so this was a problem.  I couldn't take all liquid into my pipette, so i had no seperation. What i was basically doing was sucking up the top layer only, so this was my fault. after aa couple of tries, i just sucked up the  top layer, then the bottom layer and repeated that  for 3-4 times until there was no more oil left.

I'm having very much trouble with measuring the right amount of liquids. I tried to convert the amount somehow to drops, but the drops from my pipette doesn't compare to the drops from the bottle. 0.5 ml oil wasn't 18 drops like you said, but more like 30. But maybe i was holding the syringe in a bad angle. I doon't know.

I need to measure:

10ml oil = x drops

10ml of water = x drops

10ml of DMSO = x drops

Always using the same pipette. Then I'll be able to perform the tek accurately. Maybe there is some stuff in the oil causing bronchoconstriction. So next try i'll double the dose, work more accurately and have chocolate and coffee handy. I did drink some and it seemed to help a little with breathing.
