I have just started using it as well. I have been doing 1/4 cc eod (1mg). Since you are worried about taking too much and want to use 1/8 why not draw out 1/4 and use half, keep the rest in the pin and then use the other half on your next doseage. That way you will get the right ammount even though the individual doseages may be off by a drop or so.
