My left breast is a b!tch

I have way too much milk in it and an overactive letdown that ends up drowning my little man! Feeding on the right side is great- easy as pie. Trying not to pump so my supply regulates itself but have to hand express just to get LO on the breast. We are nearing 2 weeks old and have started block feeding 2 feeds per breast which works well on the right side but not left.

any tips? I just want to give up feeding on the left side.
