Coffee timing, apportioning

I have been taking 1/2 spoon of instant coffee at 6 AM and at 1 Pm, to keep up my productivity.  I am not taking any meds.  I noticed I was less productive in the evening, so I have been taking 1/2 spoon of instant coffee, at 6 or 7 PM.

I am still not getting a lot done in the evening, but another 1/2 cup of coffee at 6 PM helps, to some extent.

I often get up early in the morning and get some things done before I take my 1/2 spoon of instant coffee.  I am trying to be conscientious about taking coffee regularly, becuase I have periods of irritiablility if I get off schdule, and miss my morning or afternoon coffee.  My job depends on my being pleasant to people, so Lack-of-Coffee irritability is counter-productive.

I often go to sleep shortly after I get home.  I get home around 6 PM and will sometimes go to sleep at about 7 PM, and get up earlier in the morning, say 4 AM.  I don't have to get up till about 5:45 AM, so I have some time to sort mail, and look at bills, read the news.

I am trying to get myself content with doing som little things, because I often do nothing, just thinking of ways to either accomplish big things, or how to get around doing big things, and then nothing gets done, because I spend too much time daydreaming/planning instead of chipping away at little things.
