I've been gradually getting sick, so experiment: failed. I don't even know if the headache I had last night was from the caffeine or this fever, but I'm definitely not in shape to do any chemical experimenting right now. Sorry folks!
I have a feeling it was either too high of a dose, or I'm just not the right person to be taking it every day. It could possibly be a once-every-so-often supplement, like how I was using Ambien a while ago.
