Something that helped me in the past was playing that ridiculous car game from when I was a kid, the one where you start by saying, "I'm going on a trip and in my suitcase I will bring", and you start with the letter A and say _______, then as you move down the alphabet the list gets longer and longer and you have to try to remember as you go. I used when I was extremely pregnant and so uncomfortable and irritable, not to mention anxious to NOT be pregnant anymore, lol. I never made it past about K.

Example :

On my trip I am bringing an apple. On my trip I am bringing an apple and a bear.
On my trip I am bringing an apple, a bear and a cat. etc.

Using something harder than apple, bear and cat uses up more of your brain which tends to help the process along. Like aardvark, beluga and caterpillar for example.
