Is there any point in doing the Sleepworth test if he is not tired during the day?
Suppose there is if he is honest with himself.
You need to go back to your GP and talk this over with him.
If you have put on some weight and the snoring is getting worse, you may be about to get hit with Sleep Apnoea. If you have it already it may be mild for the moment, but will get worse if you put on weight, then it will really hit you.
It sneaks up on you, you don't notice until you feel tired all the time.
It is now you need to take action, loose weight, go to your GP and ask for a study.
If nothing else it will rule it out for now.
If you have mild Sleep Apnoea you will be encouraged to loose weight as this is often enough for most, but not all.
Go back to your GP and ask to be referred for a study.
He may want to put you to ENT (ear nose & throat) to start off with, but go to make sure there is no other problem. Be very suspicious if they offer an operation without explaining what it is for. Suggest to them that your partner say you have Sleep Apnoea events during the night as well.
They may not refer you to a sleep clinic, but they will usually ask your Gp to do that. Sleep Apnoea can be very dangerous if untreated, heart attacks, strokes, and not to mention driving when tired.
