FLAC isn’t too bad on disc space.

I imagine that a floss pick is better than nothing, but string floss is the best way to go about it. Proper flossing technique requires you to be able to have a small amount of slack so that the floss can wrap around the contour of your tooth and slide past the “triangle” between your teeth. The floss picks are too taut to be able to do that adequately.

I’ll also say that I completely agree with OP: picking up a good flossing regiment helped my mouth health immensely. It also helped improve my gum health and made my teeth feel “tighter” in my mouth, not like they were always a little bit loose.

When I took Vyvanse I couldn’t eat grapefruit. It made me throw up and then I developed an aversion to it, and even now almost a decade since I stopped taking it I still really dislike grapefruit. I’m not sure if it’s because of the citric acid content or what else, but oranges didn’t ever bother me in that way.
