I seem to be drinking an awful lot of tea this week. I know why too. I've been under a little more psychological and physical stress than is good.
My coping strategy under these circumstances would normally be to eat too much rubbish food. This is something that I am trying to deter myself from. Nothing wrong with a treat but stress eating is not ideal and I really do not enjoy it. Often I will substitute chewing gum, I am trying to limit that too.
Getting better at politely and firmly communicating boundaries and drinking lots of tea seem to be the go.
I recommended plain black tea and flavored tea with milk. You can get great flavors by popping in a herbal tea bag into the cup, or pot.
