Coke, Caffeine and Sleep Disruption

Coca-Cola-LogoI promised an update earlier on regarding the diet coke situation, and this is it.

Just to set the scene for those of you who are new to my ramblings, I have spent the majority of the last 25-30 years drinking mainly sweetened (sugar or artificial) soft drinks of some sort or other.  Diet coke has been the mainstay of my life for at least the last 15 years, and I’ve recently broken what I can safely say was a dependency – read here for more on that.

At first I abstained completely, then I dipped back in occasionally, and I’ve now been dipping in and out for long enough to be able to draw some firm conclusions from it.

  1. First of all, if I drink a small bottle or glass of coke while I’m out (diet or regular) then I can function perfectly normally.  I don’t feel desperate cravings to buy another one, and it doesn’t seem to affect me in any other way.
  2. Secondly, If I buy a large bottle of coke for home (diet or regular) then I’ll really struggle not to finish the bottle in one go.
  3. Thirdly, if I have more than a glass/small bottle of it, my sleep is really disrupted.  I can get off to sleep ok, but I will wake again after a couple of hours (oddly enough at around 2am every time) with an actual buzzing in my head.  I’ll struggle to get back to sleep at all, and what sleep I do get will be disturbed.
  4. Having had more than a glass or small bottle of it on one day, the next day I will feel cravings for more

I’ve noticed similar cravings from other fizzy drinks recently, but without the sleep disruption, which I presume is down to the caffeine (I don’t drink coffee so this would be my only caffeine intake).

So what does all that mean?  It probably means I shouldn’t be drinking any of this sweetened crap, but if I do, then I need to carefully control my intake of it.  More than a glass in a day and my ability to control the amount I drink after that is weakened considerably, and if it’s coke, then I’ll struggle to sleep.

That’s all for now – more as I think it.
