I am 55 yo male, with mild anxiety. I just hadA buffett, Asian food with non sweet ice teaand I have the jitters. My back tongue feelsheavy and a bit numb. It could be caffeine from the tea. However, this often happens after every large meal regardless whether I have tea or not. What is this?                               Thanx,  Dan
