I got nearly got harrassed into cutting mine off, after having kids, but I just bought better bras and focused on strength training, and I now have no problems with an 80H.
Just avoid any bra that carries the weight on your shoulders. Should be spread entirely around your rib cage, so that the straps are just there to hold the material up. Or just wear a good sports bra.

Another thing that's really comfortable is wearing a corset over a button-down shirt. Feels weightless. Also looks good. 

 yes to corsets when they are made well and fit right.  

 People think they're just fashion accessoires, but a real one is very comfortable, even if it's just stiffened with sailing cloth or brocade. Disperses the weight.
