Does coffee make anyone else feel more than just jittery and awake?!

i haven't drunk coffee for years because of what it used to do to me. It gave me heart palpitations and made me feel all hyped up and jittery like some crazy little dog running round in circles. I loved the aroma and taste but hated what it did to me and after some really bad heart palpitations I stopped drinking it completely and switched to a coffee substitute called instant chicory.

Yes, When I as younger, I used to drink many mugs of coffee, Pint ones in fact. Since then, although I am still drinking coffee, my doctor tells me that it is bad for me, makes me, feel a bit unwell at times, if I have had too much. I have to have tea for a while, Mark

It makes me sleepy, a cup before bed usually means I sleep like a baby.
I've had all the jitters, dodgy visuals and twitches from having a few of those Relentless caffeine drinks one after the other.

it makes me go woooooooooooooooooooooooooooo
