Please do not try desiccated thyroid first of all. The best way to test if you need some thyroid is to use basic T4 first. See how it goes and use a small amount to start with (25mcg). The smaller amounts will complement your own production and so you won't get to the stage where the body is shutting off your own supply. This is really micro dosing and many people would benefit from this practise. Being 40 odd means your bodies production has slowed down and it will get worse as you age.
T4 only is often all we need (certainly men because we have cleaner livers and less oestrogen to interfere with thyroid production). Some other people think T3 only is the first port of call. This could also be an option, but make sure you only use tiny doses here (more so than for T4). A good starting dose is 2.5mcg
NTH comes with too much T3, hence why it is better to try and see how T4/T3 work before you use natural. People who have had the thyroid killed or removed do best on natural. It sounds like you have classic lower thyroid features and so you need a top up. It is likely to be permanent and you want to find the correct level without jumping past your sweet spot.
Also try taking the thyroid meds (if T4) at bedtime or in the evening. This will help sleep and better replicates when we make this hormone (first part of the night). This will have a knock on effect of improving adrenal performance. If using T3 take it in the morning, but some people do find T3 at bedtime better as well. The only issue you can get with T3 at bedtime is the greater stimulatory effect than T4. IT can keep you awake. Trial and error is the best approach.
