Some "common sense" suggestions: - move closer to job - work sane hours - change your job - arrange flexible hours with managers to travel off-peak
Something "controversial" - there were some threads about nootropics - some people say it's a "zero sum game" - taking credit from your brain bank account... Look at Modafinil (over the counter from online pharmacies).
I find it helpful to use a text-only interface and use tmux along with a tiling window manager. But basically, learn how to use your computer without a mouse. It takes a long time to get comfortable with this setup, but it pays incredible dividends when you finally do (well... for example 2 hours of your life back every day).
With the off-peak thing, one suggestion would be to get to bed super early and take the first bus/train in. This tends to be the least susceptible to problems. It's also easier to sell the boss on the idea of starting at 6 am rather than 11 am. The trick is to have the internal fortitude to leave at 3 pm. Assuming you work in the city and live further out, this should allow you space on the bus/train to work.
Suggestion which may not be practical: get up 1 hour earlier? So move the sleep time forward so you get some but can do some personal work.
I don't accept more than 1h commute total per day, or ask for remote to compensate.
I commute just under 2 hours each way to London. All the work is in London. I used to live in London when I was younger. I would rather jump off a bridge than live in London now.
The way to compensate is by working partly remotely. That way you get to enjoy the place you live at least part of the time.
We all make choices, mostly they can be undone.

Up here in sunny Brum: you could be back up from London in 1h30 on a Pendolino and still live in a leafy suburb (15 min local train from New St gets you to the half acre garden territory).
