I've been using the pump for more than 3 months now....I did the conditionaing period and all that.. but I dont pump everyday..now and then....is that why my lips dont stay plump for more than an hour or so.... I have to be very aggressive (hard pull and long) to get the plump that I want....and then ill bruise....WHAT DO I DO TO STAY POUTY FOR A FEW HOURS? I drink a lot of water normally and am very healthy.....HOW DO YOU GET A LONGER PUMP?
