Hi Sasha Nico.
I wish you the breast of luck. I used BB, years ago with no success and it did strange things to my body. I empathize with you on the thyroid issue as well. I even tried to supplement with kelp/iodine and it pretty much knocked me out, like I couldn't wake up after always having been the hardly-need -sleep, hyper girl.
I don't know if you have tried massage, but I say that has been one of the most successful things I have tried. Katana and SweetAlyssa have some great and inspiring information of their threads. Also, there have recently been posted, some wonderful video in this forum. Here is an interesting thread from just a couple of days ago, for example:

Along with subliminals I listen to via YouTube, massage is what I am NBE-ing with lately and I would say, massage is the real deal! In the past, I tried various massage techniques, but I think now I am doing them right. I hope that helps and gives you some inspiration.
PS: It was literally the other day that I realized my boobs have definitely changed this month. It sneaks up on one. Well, I looked at my bra (I get bras based on what looks like it might fit from thrift stores. I was shocked! I was lazy about it (because in the past I made serious efforts with maybe the wrong kind of massage), but massage is worth the effort!
