Sorry Dalene
I am also experiencing some days of exhaustion and insomnia, think it does comes with baby growing and the due date coming closer.
For exhaustion I still occasionally only on the days I am extremely tired I use 1 teaspoon blackberry elixir in half a cup of milk, it does help a lot for energy and exhaustion, its safe while pregnant and breast feeding stages.
Unfortunately so far only cure for insomnia is catching naps during the day when I can. Cause I never get a full night sleep anymore between the 4 yr old and the preggy belly.
Also remember you have a lot going on my dear with hubby and helping him, so I am sure this is also giving you insomnia and making you exhausted its a lot to deal with when you pregnant, rest when you can, maternity leave is around the corner.
Always thinking of you hope your phone gets sorted soon.
