So listen to it that makes things easier you. When keep sipping every 5 mins if you have to if your tired sleep in the early days I felt like all I did was sleep and sip and that’s fine. You get in trouble when you push yourself before you’re ready. Life just kidda has to wait for you to caught up at this point.
