If you are not breastfeeding, I will recommend Liproxenol max. Me and my friend have proven it to be very effective without any side effect. I had my apprehensions at first but this product has delivered what it claimed. Sorry to rave. :)
Are you breast feeding? If so you have to make sure your eating enough to keep your supply up. If not cut back calories, eat more fruit, veggies, lean meat, try and eat as cleanly as you can. Walk as much as you can. Put the little one in stroller and get moving....
Good luck and keep hydrated with water.
