Robin, still bf here at nearly nine months & no intention of stopping, so I can't help you with an answer to your thread title.
However I did just want to add a few thoughts.
You know, you don't have to wait until your dd wakes to feed her if your boobs are uncomfortable. Watch her sleeping. When she starts to stir a little, not waking stirring, just sleep shuffling stirring, in her sleep, lie her next to you and plonk your boob next to her mouth. She'll latch on and suckle in her sleep, relieving your discomfort without waking her at all. I believe it's known as a "dream feed". Once you've done that, get up, have a shower and get dressed while your dd sleeps, with nice comfortable boobs.
Biting - well, I would be lying to you if I said I hadn't been bitten a few times, but only once was it hard enough to make me wince and that was an unusual situation where I was bf handsfree in a sling and holding shopping bags in each hand so could not remove nipple from teeth quickly enough!
Clothes - if you have the money you could splash out on some special nursing tops - type "nursing tops" into ebay.co.uk and see if you can get anything on the cheap. That way you can wear what you like. You can even get nursing dresses. Mamanana has some gorgeous nursing wear, pricey but if you want something special it's worth thinking about it.
In just another six months' time you will be able to give cows' milk instead of making up formula feeds (if you want to stop then) which is a lot easier... you've done six months, it's only the same again.
Then again if you are sure you want to stop, you have to do what's best for you.
If you long to get back to wearing nice bras, why not try one of these? It converts any nice bra into a nursing bra. (If you're prone to blocked ducts it's best to avoid underwired bras.)
