After 4 long months, my OS is finally gone! At first I was confused and thinking that I'd lost my supply, but since my baby's diaper output is exactly the same I knew that couldn't be it. For the first time EVER my daughter seems to really enjoy nursing, no more gagging and choking and inhaling milk! I can't believe that nursing can actually be like this. We actually did every single feeding in our bed for 2+ months, lying down, because she absolutely refused to latch on any other way. She doubled her previous weight gain in the same amount of time as a result, we had switched to this style right before her last weight check (very low gain).
Just want to say to anyone out there who is still suffering, that there is hope. I did not pump except to relieve engorgement, and my baby has never had a bottle (she refuses). I am amazed that my body finally got rid of the extra milk, and I feel like I finally trust my body to take care of baby. She even nursed for fun/comfort in the living room snuggling sitting on the couch with my toddler, which has never happened. It was like a dream come true. Hang in there, all of the OS mamas.
