I've pretty much got the basics down, ie - same time everyday, 3 hours uninterrupted sleep, clean before and after every use. We have shared parenting of my stepdaughter so 3 days of the week I take her to school, the other 2 her mom does. She normally wakes around 7 but it can be anywhere from 6-7 so I've decided to temp at 540 and go back to sleep after. I'm cd 4 today & just received it in the mail so I will be starting tomorrow (perfect timing as af is just on her way out). It says on the box though for oral use only so I was wondering if that matters or if it's just a liability thing for the company? Thanks in advance ladies : )
