Anybody dealt with serious <1G sensitivity?

Trying to get my PPL and eventually fly heavies but I’m finding that I have a serious issue with negative Gs (anything less than 1G). Without diving too much into it, it’s bad enough to where I’m not allowed to solo until I can get it figured out. Has anyone else found a way to overcome serious negative G sensitivity?

As a side note, how often do you experience any sort of negative Gs during any normal flight (not aerobatic or anything like that, just standard point to point)? Just during severe turbulence?
