Rooster, just hang in there - it is worth the wait, and she will never forget that you tried to stay at her side all the time once things get better. Working overtime seems to be a normal state of things these days, bur what is thrown at ther simply is too much, and IMHO this causes her sleeping problems and cannot ne cured by pills. Try to make a deal to get a vacation time together and a definite statement for the assistance later this year, because reducing that amount of work is the only cure and will save both your heath and marriage. I will cross my fingers and pray for you, ask only for enough strength to master the next day and you will get through. My wife and I had similar problems with our working situation and got through, and now we are in happy retirement, so will you!
