Stop at the big boy restaurant, get yourself a chili size and about 4-5 cups of coffee. After that make sure you have easy access to a restroom and lots of toilet paper
Activia is crap, loaded with chemicals and shtuff you cant pronounce. Get some Greek Gods yogurt. I love the black cherry flavor, but they have a few others.
Sounds like you need to get out and walk a bit.Otherwise try to identify any other habits different from home time.
Brew coffee. Drink 2 glasses of water. Drink coffee and a cigarette if you like. Head to bathroom. We’re all different.
Metamucil caplets every day. I learned this years ago from a friend at the gym. Do u want to take a single large poop every morning and be done with it? Try Metamucil daily. It seriously works.
Water, lots of veggies (snack on them rather than the other crap most drivers eat while they drive), prunes, licorice.
The trick is all in the timing; eating cheese and nuts and meat when you're outbound, then switching to veggies, fruits and licorice on the return. Heaven help you if you get delayed on the return though...
Wendy s chili works wonders. Or you could also drive anywhere in the Midwest, Nashville, or Atlanta, Drivers in those areas both cars and trucks, will keep you regular with all the stupid stuff they do will scare the crap right out of you lol
