I had the 45 minute DMPS IV drip given once a month for 6-8 months (I think) some 12 yr ago. Was told to expect ďfeelingĒ worse for a while as the mercury is stirred up before excreted. Within 2 months, brain fog lifted. Also, I had been so tired in the past that I took an afternoon nap 3 X week. That tiredness went away for years afterwards. A good Colon Cleanse should have been recommended as part of the protocol.
