Shauna,
I think you will be just fine.
I rarely follow my sleep times bc I end up staying up late not bc I can't fall asleep, I just want more time in a day
I am having tremendous benefits from the modules I am on.
(Btw for anyone who does not know, you can e-mail PATHS to ask them to change your sleep times if you want up to once a month. In addition there is a flex system for people who frequently need to change their sleep times like pilots.)
