Hey Kristen, when the laxatives don't work try "magnesium citrate" they sell it at the drug store, grocery store, walmart, etc. Over by the laxatives. It is a liquid. Usually in a green or red see through bottle. It will do the "trick". I only used when extremely necessary and if you've taken these laxatives and still aren't going, it seems extremely necessary.
I have not gotten backed up since I stopped taking the extra vitamins. Still on phen, but everything is running "smoothly"
Now, regarding this issue, I had discussed it with the doctor when I was going there and he said that it is ok to take laxatives while on phen because once you stop taking phen your body will return to normal thus not "needing" to continue taking the laxatives. Since the phen is causing it. So it isn't like you will become dependent on the laxatives. Take away the phen, no need for the laxatives.
