Advice I will be heeding from here on out:
Always add lemon to your water
Drink a glass of lemon water first thing when you wake up.
It "helps flush out the liver and kidneys. That extra squeeze of fresh lemon juice will encourage your liver to produce bile, stimulating digestion. Lemon juice also keeps undigested nutrients from entering the bloodstream, meaning the liver doesn't have to work as hard. Lemon juice is also rich in antioxidants, which remove toxins from the body."
