So I had a really hard time getting to sleep last night. I didn't get to sleep till about 2 hours b4 it was time for me to wake up so I took some nitro2go from the gas station. I didn't drink any coffee my stomach has been acting up and I didn't want to make it worse so I just grabbed a 2liter water and a pack of those caffeine pills and called it a day. Ever since they started kicking in I've had the shakes. I'm pretty sure it's the pills but my concern is really how do I get it to slow down? Or how do I stop feeling jittery
