The alarm went off at 2.30am and I woke surprisingly easy, although I did find myself lying in bed wondering why am I doing this.

I can already see how most people end up sleeping to long during the transition period and how that would stuff things pretty quickly. Actually finding the motivation to get through each hour of these first few days is going to be critical.

I think the next couple of hours may be spent writing down some solid aims and ‘success criteria’ for this trial as that will almost certainly help me get out of bed from the next few sleeps when sleep deprivation takes hold.
