When they did have it and we knew it we just called it the shakes. It was clear for some. They never were what we called normal. Many others endured and functioned as best they could but manned up and carried on.
As I typesetter, I worked for a small farm magazine in Missouri in the mid-50s. One of the ladies came in late one day and someone asked "Jim again?". She said "Yes, he woke up crying again." Evidently this was not an unusual occurance.
Later on I found that "Jim" served on one of those rocket launcher ships and his job was to remove the duds after a salvo went off. I thought of the EOD guys disarming a bomb, as sometimes (I was told) the rocket went off when you were pulling it off the spigot. Talk about MAJOR stress.
