I will give you a similar example. My SIL, a highly respected and decorated BS RN nurse got roped into a claim that vitamin infusions which were not approved by the FDA and only given in Canada were going to cure her 50 year old husband's terminal cancer. Then she was sure radiation, not recommended byMSK, would work. $10,000 later and 5 years after his passing, she voiced how desperate she was grasping at straws, anything to stop the progression. It's unfortunate and I feel your pain. However, you don't want to harm your husband. It surprises me that lithium is legal without a Rx. It can be toxic to the nervous system.
