Hi Paulette- This is a slow process. As you fill up your body with good minerals the heavy metals will be dumped as the body sees fit. The body decides when and how fast it can detox itself. Not just from heavy metals but all stored toxins.
This is a program for life really. Eating the cleanest diet, detox baths, sauna, enemas, eliminating stressors, some supplementation and some excercise as the body allows.
P.S- Keep in mind that you have also just stopped taking anti-depressants a few months back. This in itself takes awhile for the body to detox and may cause additional fatigue and other symptoms. At least it did for me for many months after I quit.
