I'm cutting nicotine and caffeine for a month.

I did blood work and realized I had low T -- did stuff to improve it and I see much better motivation and drive now than before, but it still isn't internally driven. 

My theory is: cutting stimulants will improve baseline dopamine.

It'll basically give raw power back to me for stuff I need it for, rather than wasting and spewing motivation juice out randomly by spiking it externally. 

Going cold turkey and using ltyrosine as a substitute for a couple of days to soften the blow.

That's the theory, time to see if it actually makes any sense.
