Between reading this discussion here, another one elsewhere, and having two coworkers talking about trying to quit caffeine it was on my mind. Two months ago I decided to quit it mostly just to prove that I could, to see if it was tough, and see if I actually felt any different or if people were just patting themselves on the back over quitting what they perceived to be a bad habit.
I found completely quitting coffee drinking didn't work as I needed another beverage but didn't want to drink anything else. I switched to drinking decaf instant coffee which allowed me to continue the drinking habit though I would say I have cut down on drinking even that as well. Firstly, I had no withdrawal symptoms as far as I could tell. From being a heavy coffee drinker for the past several years and moderate for years before that to essentially cold turkey and I didn't really notice anything negative. I think day 3 I took a late afternoon nap and other than the change was quite imperceptible at first.
After not too long I began to pick up on a pattern though, I was falling asleep much faster at night and I was waking up feeling well rested. Yes, my sleep absolutely changed for the better. I had no idea caffeine was affecting my sleep so much, I mostly did this to prove to myself that caffeine wasn't all that big a deal but found out it had been affecting my sleep quite significantly. The biggest negative change is I don't get to lay in bed listening to relaxing videos at night anymore, I just get in bed and go to sleep. When I wake up too, I seriously feel fresh, I was so used to those days where I woke up feeling like a zombie I thought that's just how I was in the morning some days, turns out not. I've been getting up and I've been feeling good. I really can't recall not feeling above average in the morning for the last 2 months, that's pretty amazing to me.
I have decided I will still allow myself caffeine before a morning workout or physical activity if I want to go hard, otherwise I plan to stay away from caffeine from now on except when specifically called for, no habitual use. I don't plan on going around and telling everyone they need to quit caffeine now, but boy am I happy I tried quitting it myself. Thanks to everyone in this thread for being part of the discussion that sparked me trying this change!
