I'm with genetic on that it depends on your own body chemestry if the coffee and energy drinks will effect your mood. I don't think it effects me, but I sure do think it effects my mother in law, (although with her it is soda and not coffee, like she can drink a 12 pack in one day....) And she has the other leg to the stool with the cigarrettes, too. And yes cigarettes definately effect her mood a ton. When she doesn't have her cigarrettes she turns into a pot of slow boiling anger.... I hate being around her when she's like that, but I hate that she smokes, because it's terrible for you.

Plus I heard somewhere recently that cigarettes actually trick your brain into thinking you're calming down, when in fact you're not. Your body is still responding to your stress but it tunes your brain out. So, smoking to relieve stress is like the worst thing you can do because it addicts your brain but your body gets 0 releaf.

Sorry my spelling isn't so good I'm noticing.... I'm quite a bit off today.
