Hey hun, careful pumping hard enough to cause pain, well it depends where the pain is. Is it coming from the entire breast or just where the rim sits on your chest? If it's from the rim, it could be just that it's hitting your ribs and at first this hurt me also, I used the campers tape method for padding for a while, and now I don't need it and the rims don't hurt anymore. I get to the 1 inch mark with full breast touching, my nipples go to about the 4 inch mark in the XL's I measure on one of the cups cause the other one I think the ruler on it is a bit off. And I drink coffee, if you aren't doing herbs you don't have to watch your caffeine intake, I just wouldn't take NBE supplements around the same time you drink coffee, soda, or any other type of caffeine, like do it 30 min after or 30 min before type of thing. The only time caffeine effects NBE is with herbal NBE because herbs work on swelling the breasts then over time the swelling becomes growth, and it swells by using water, thus why caffeine and herbal NBE doesn't mix well. Now as far as BO goes, it depends on what kind you want to go with. I would read up on BO on this forum http://www.breastnexus.com/index.php
There are two main brands most use, that's Ultra Breast (which I take) and the site is www.medplex.net, there is Bountiful Breast which many others take www.bountifulbrest.com is their site, and there are plenty of "generic" brands to choose from, swanson vitamins sells one, vitamin power, ultra enterprises, and there are a few others, just check the forum for your options. I went with UB because I heard it worked for others, it was much less than BB, and it had the higher dosages of BO per pill compared to generic brands. I'm on my 6th bottle and grown 2 1/4 to 3 inches, waiting till after my period to say for sure if it's 3 inches. Just do your research and determine which one you want to try. Hope this helps! And good on you that you found something better to do for work.
