I just got my SOE gel and I remember reading that you could get multiple uses out of each packet... is this true or am i just imagining things? How much of the gel do you think I should start out with?

And... I also got AE/m, any suggestions on whether i should try SOE or AE/m first? Any suggestions on where I should apply the AE/m and SOE to try out first? (and also how many drops should i use of the AE/m first).
