hi gals. swannymomma--personally i wouldn't feel comfortable doing something like that while breastfeeding. depending on the age of your baby, Primal Defense by Garden of Life is an excellent probiotic which will detox you. i am currently breastfeeding and have had much the same situation as you. my digestion was such a mess and body depleted from all the pregnancies and BF. you will probably want to use the powder (very tiny scoop and easy to dissolve) and start with just a tiny bit, like maybe 1/8 of a scoop. stay with that amount for a week or more and watch your baby for signs of detox (stinky stools, fussiness, extra spitting up or vomiting). then increase your amount just a tiny bit more for another week. continue to do this adding a bit each week. any time you notice something with your little one back off. this is what i have done and so far am still under a whole scoop but plan to go with the whole usage schedule when done breastfeeding. (my little one is 10 mo. also!) this will not cost you near what your dr.'s plan would. another thing i have done is went to my local chiropractor and had weekly accupuncture which helped a lot. my ins. doesn't really cover it, but something about the way the billed it, it was covered! i did that for several months, but it is different for everyone. it doesn't hurt much and is even relaxing. i always felt refreshed afterwards. i have found that the PD caplets do not break down as easily for me, the powder is more readily used. and you can start with much less also (one scoop=one caplet)
Julie--i believe it's ok to begin with Primal defense when pregnant and much easier than when nursing.
i have also used it mixed a bit with applesauce for my kids to boost immunity and better their digestion. (it's dark green and makes their applesauce fun!)
there is a practitioner locator on the Garden of Life website where i found an excellent Dr. i called him several times over a six month period and of course he was busy but always returned my call, on his dime. my hubby didn't want me to go there (a five hour drive) as we had already done that and gotten burned in a way. so i followed this dr.s' advice which led to the accupuncture. you might be able to find someone in your state who knows about the primal defense. i'd be glad to help in any way i can.
