Oh yeah sleepie I'm guilty of this one I've been on decaf again now for a few months with some random caffeinated days. Well then yes I did not sleep well the night prior so I took 100mg of caffeine then today I did it again gulp... I'm hoping I'm not starting this nonsense up again but I might be lol. For me it starts of great but after a week or so I start having issues. I mean I guess even on day one it will cause my Ming to race and my anxiety to go up.
It's a back and forth battle for me and mainly because of sleep issues sigh
