Hrrrmmmm. Coffee-related question. :P

[sunnyskies]

My stomach has been weird for the last hour or so and I had sort of a loose/soft BM (tmi as always sorry, but it wasn't d*) but now feel jittery and hungry.

I woke up late and had my usual small breakfast of toast w/ peanut butter, an orange and a cup of coffee... but this weird feeling is becoming more common and I'm wondering if it's the coffee. I haven't had lunch yet, since I ate this other food just a few hours ago.

Common sense will tell me that it's the very low-cal, small breakfast to blame for the hunger, but does coffee upset anyone else's stomach and overstimulate your nerves ever? To give a strange, jittery feeling? I drink it instead of soda now because I feel like it's obviously healthier and gives a better buzz, and I have some caffienated teas I could try instead.

I just wonder if it's a bad choice with how little I eat.. seemingly affecting my stomach and also making me nervous and shaky. And of course I'm emet, so I'm also hoping this is all related to my food/beverage choices this morning and not a virus, hahaaha.

Point of all this babble: Should I just stop drinking it if it has this effect?
