Johnny Manziel says he was initially EXCITED about being drafted by the Browns -- but when he finally got to Cleveland ... all he wanted to do was leave.
"Once I landed and went to Berea, Ohio for the first time, I was like, 'Can I go back to college?'"
"I don't know anybody, I don't know where I'm at. It's cold. I don't like it," Manziel told Kevin Hart while taking an ice bath on his show, "Cold as Balls."
Manziel opens up like a book to Hart -- talking about everything from his drug use in college to wanting kids with his new wife, Bre Tiesi.
