It is possible to get a caffeine overdose. If you have symptoms like shaking and anxiety, then it is possible that you have an overdose. If that is not the case, then do not think too much about it. Also you will recover from the caffeine after some time. Wish you a speedy recovery.
Hope this helps you.
