Was going to say the same thing. I'm 44 and feel like someone's blasting me with that Men In Black brain eraser once a day.

I also sleep like shit. 3-5 hrs for weeks on end.

I have about 3 hrs of work to do today. Normally I'd wait till everyone is in bed, work on it till 3am, then 'sleep in' till 7 so I could be ready for work.

Now I'm just doing it midday so i can go to bed at a normal time.

(Actually i'm procrastinating currently, another bad habit that i've developed by telling myself i can just do the work when everyone goes to bed).
