Eluding Tuonela

I've always had a difficult relationship with caffeine. I never got into drinking lots of coffee as most Finns do but instead I've consumed lots and lots of caffeine in Coca Cola (Zero), energy drinks, and caffeine pills. I also love maté products like Club-Mate. I quit both coke and energy drinks pretty much cold turkey about two years ago and I've been mostly avoiding all caffeine products (even high-caffeine tea) most of this year. 

It's been slowly creeping back again and today I noticed that I reliably get a head ache in the evening if I don't take my daily dose of about ~1-2 coffee cups worth of caffeine (~100mg) in the afternoon. This is highly annoying and one of the reasons I've wanted to avoid it in the first place. But I also really enjoy the benefits of a strong focus and energy boost it gives me, which helps a lot when working (and I'm so used to it that it feels really hard to not have that).

The other negative side effect of caffeine is the negative effect to the sleeping rhythm. I need to be careful not take any caffeine at least 6 hours before bedtime
