Three 250mg DMSA tablets, on one day of the week, every week, for three months.
This is way too much to start with! I'd suggest to start with 25mg DMSA. You should take it every 4 hours, because it has a half life of 4 hours.
The reason why you are more fatigued is because you are moving the lead around without actually getting rid of it. There is a reason why you have lead toxicity. Most likely, your body has a hard time to get rid of it, so there is no point in moving so much lead around at once.
I'll read up on the Cutler protocol when I have the energy.
The cutler protocol is pretty simple:
Use 25 mg (or more) DMSA every 4 hours 3 days on 3 days off (or longer).
Supplements:
• Vitamin C troughout the day.
• B50 or similar multi B vitamin.
• Vitamin E 1000 IU per day.
• Flax seed oil 10-30 grams per day.
• 200 mcg chromium picolinate with each meal.
• Magnesium 500-750 mg elemental equivalent per day in divided doses.
• Milk thistle extract 3-4 times per day.
The supplements are not that important and are mainly there to relieve symptoms. The most important part are the chelators and the antioxidants (vitamin C and E).
