@tomaszpl Many great ideas here. I would add this. Make sure you're honest with yourself. I'm also in sales, working at home. Don't have youg kids anymore, but they were once. I've managed to make it work FOR ME despite these things:
Have never been inside a gym.
Watch less TV, but still watch plenty.
Eat less, some days a lot less, but still have pizza, wings, etc. But not nearly as often, a lot less snacks, almost no crappy snacks, no soda, sf coffee creamer.
Will not give up beer. Weekend only, but still...
Will not workout in the morning.
For me, its about finding 30-45 minutes every day after work. I have the luxury of knocking off a little early. And I work my ass off during that time. I don't count calories, but many days I would bet Im at 500-700 calorie deficit. I will have a bad Friday sometimes, I don't let that stop me.
Bottom line, you HAVE to figure out how to make time and eat less and healthier. Get a full vloodwork test and take appropriate actions with that. Take a sleep test, because what's the downside? Just do it.
Wake up tomorrow and say fuck it, I'm going to do this!!!!
