It never occured to me to count drops because it can be easy to lose count.
I'm sitting here with a friend who started at 120mg too and she is counting drops from a little more than a half of a dropper to get to 120mg... meanwhile I'm using like, 4 times as much and thinking I'm taking 120mg!
I should probably get a measuring spoon and measure it by the ml to be sure. If .75ml is 48 mg, then I would want almost 2ml. That should put me where I want to be.
