High stress job
Hockey 2x/week
Weekends full of housework
Pound energy drinks
And you don't know why you're exhausted all the time?
You need to revamp some things, restructure your life a little. You can't be "ON" all the time, where's the down time?
A lesson I got from my grandparents (that took me forever to understand) was slow and steady - do a little every day. So rather than save all the housework for the weekend, do a little every day. Then there's a little less for the weekend.
The hockey is good as exercise and something you enjoy, but it's also a lot of time. Not saying that's all bad, just something to be aware of.
And just stop with the energy drinks.
