If that is the half life... then its simple: ignorance.
ED is going to give you more even levels, and that is pretty desirable. But with a half life like that, every day or every 3rd day is fine.
I guess it helps to take a little bit every day instead of a lot at one time, for when you start it... you'll notice the sides come on slower and they will be less intense, if you're gonna have a problem.
