Most of the time when i'm asleep, i would sweat, this gasbbeen happening for almost two years?

Gasbbeen?: 36 y/o says, Most of the time when I'm asleep, I sweat, this "gasbbeen" happening for almost two years? Not clear if one is saying : Gasping like in "gasping for breath"; Snoring or even Flatulence (passing gas through the anus). Or "gasbbeen" a mis-statement for ("has been" ) sweating at night for 2 years. Answers depend on how we understand the questions, So please clarify. Thanks
