I normaly have like a bad breath white stuff on it that i brush off my tongue
, but this time it was black. The day before i had some hot chocolate and
a dounut and some of the usual stuff, soda, tacos. A few hours before i went to bed i had heartburn. I've felt that before so i thought, maybe there isn't enough acid in my stomach to digest the food so i had some lemon juice. Then it kept hurting so i took some Peptobismal.
