Constant urge to stretch when drunk

Im a 23/f and have come to notice I get this near-constant urge to stretch my arms or legs when i’m drinking, usually a little after the point of being tipsy. Even if I do decide to stretch, the urge/feeling to keep on doing it comes back within seconds to a couple minutes. I regularly stretch due to back pain and will only feel like stretching after work shifts.

Wondering if anyone experiences the same thing or has an explanation?
