Hi Honey
Pumping does take a lot of time and commitment, but so does any of the NBE programs.
The problem with pumping is taking the time to be stuck with plastic domes to your chest for an hour, or wearing the everbra ( it thank thats the name).
Then there is the desire to increase the suction and the time. both of those have drawbacks like redness, red rings/dents where the domes were that lasts for many hours. Some other have experienced nerve damage.
All of those are operator errors that YOU must control. Slow and steady wins the race.
You also need some fat one your body. Its hard to get suction on just skin and bones.
On the plus side there is no intake of herbs or chemicals that your body has to reject, your hormones dont need to change, and you get the immediate gratification of larger breast if even for just a few hours.
The longer you continue pumping the longer your success will stay with you. There are topical 'oils' that you can use to help things along also.
And it does work.
Look at this thread on the nexum site

and dont cheap out, do some research on the suction forum, to get a sense of the best/better product.
You wont be disappointed
