Point is, weighing beans and using the aeropress helps me keep my dosage consistent so I don't go overboard.
I did this because I was getting withdrawal headaches most mornings, which is an unpleasant way to begin the day- I wasn't even drinking that much caffeine!
All these fake coffees (I’m looking at you, chicory root) taste like ash-trays from the grimiest bar in town.
I didn't have a coffee maker at home at that time. So I started getting headaches on Sunday. I made the connection eventually, after my headache completely disappeared 20 minutes after drinking a cup of coffee with a friend.
This appears to be a pretty common scenario.
Just be careful not to double dose when taking the pills.
While I'm not aware of efficacy studies of different methods of quitting caffeine, cold turkey seems most effective for nicotine and a few other stimulants.
I wouldn't frame starting up again as a failure. Quitting short vs. long term are two different things.
...then a few months later I decide to start again. Oh well. I've done the above about half a dozen times. It's fairly easy to defeat the chemical addiction which I experience as you describe (really awful headaches, fatigue, lack of concentration, etc), but eventually I'll pick it back up to get a little extra edge.
