coffee has made me all jittery, what can I do? feel terrible

[Glassofwine]

Title says it all really. I normally drink de-caff, but I didn't have a great night, so had a cup of instant coffee about an hour and a half ago. I'm feeling really bad, hands shaking, jittery etc. This has happened before, but not everytime.

Is there anything I can do to make it go away/improve? Last time this happened it took hours.

does that to me too - it's horrid you poor thing.

I find eating something substantial helps (like a big sandwich) - also drinking loads of water or juice.

can you go for a walk? work it out of your system?

drink lots of water to dilute it? eat some bread to soak it up?

you won't notice it as much if you're up and about - your heart will be faster anyway - go for a walk
