It's true.....the first day or two, it's just talking WAY too much and a lot of it is nonsensical, story telling inane stuff like about painting a wall for 20 mins, fidgety, my ex would carry around water to sip on (he rarely drank water), pacing around, checking the windows, unfocused eyes, hand feel clammy, and cold like they're wearing latex gloves, he always had to be playing on his phone or checking FB a million times, or just talkinggggg. (pretty boring to be around). After a couple days, weight loss, sunken in cheeks, no appetite, no sleep, no hygiene starts to slip, paranoia starts to set in badly, connecting fake dots, i call it, increased meanness and anger, they can't express emotions like sadness, or empathy at ALL! Basically they become a shell of themselves, it's like the devil inhabits their bodies.
