Breast Reduction

Well right now I am a 34DDD. I have back pain, dented shoulders, & an occasional rash under my breasts. I'm 23 years old & never plan on having children. I want to lose about 20 pounds & then look into getting surgery. My breasts feel huge & always have even when I was slimmer. Last year I weighed 30 lighter and wore a 32DD. I've worn so many styles & been fitted several times. I have had a significant weight change in the last year, but I think it is because after my wedding I didn't care what I ate as long as it was delicious. :/ Anyway, I would like some thoughts on breast reduction surgery. My husband is supportive & on board.
