Man, my mom did that exact thing and I swear those braids were tighter than a drum. Felt like my scalp was getting a face lift for eight hours straight. But hey, at least you looked cute for the school photo, right? Who knew torture was the secret to good hair?

Sometimes mixing flavors early actually works out fine.

That point from @barbara461 on change feeling tiring is right. A bad mattress makes your body used to sleeping in a bad way. A new one fixes the problem but feels strange at first. Your sleep habits have to learn all over again. This can make you more tired for a while. But it means you're on the way to better sleep.

Yeah the "trial" part is always so fun, like accidentally burning dinner three times. The "error" part is just me staring at a smoke alarm. Really builds character.
