Hands are shaking

My hands just started shaking about 30-60 minutes ago. =/ They're fine when I rest them on something but if I raise them (especially if I rest my wrist on something and then raise the rest of my hand) they shake a bit. My left hand isn't too bad but my right hand's kinda shivering or w/e.

I haven't exactly been eating too healthily during the past week or so and I hardly had a balanced diet today (just cereal, toast, and chicken nuggets x2); I'm guessing it could be a vitamin deficiency. If that's the case, is there anything specific I should eat before going to bed (something high in Vitamin A, B, C, etc) or should I not worry about it, grab anything from the fridge, sleep it off, and then make sure I get enough of the good ol' food groups tomorrow?

EDIT: Is this the right section or does this belong in sleep and health?

Here are some causes of shaky hands...

Certain asthma medications
Antidepressants
Parkinson’s disease
Pveractive thyroid gland
Anxiety
Low blood sugar
Too much caffiene

Eating healthy and having a good intake of vitamins can definitely help if you have a vitamin deficiency, which I'm guessing is the cause. I'd start eating better now and not wait until tomorrow. That way you might not wake up to shaky hands tomorrow morning!
