Hi and welcome to MM Menospud
Do ask to have your oestrogen and FSH levels checked. If these indicate peri meno then, as you have the Mirena already, you only need to have a little oestrogen to control the flushes and low mood. Unfortunatley nobody can tell you how long the meno symptoms will last and they often increase as you progress into post meno. Don't rule out HRT as you are young and even 5 years of supplementing with oestrogen in for 50s can protect your heart and bones for the long term. Some oestrogen would be far better that ADs.
If you've had the Mirena in for more than 4 years then it could be worth having this changed so you can start on a small dose of oestrogen as either patch or gel(Oestrogel) - I think this little bit of oestrogen at this stage would make a BIG difference to how you feel.
BTW - there is a thread for husbands on this site so it could be a good idea for him to have a look at that
