@Sancar I first had doctor outside my insurance (Open Medicine Institute) recommend and prescribe the LDN, which I got mailed monthly from a compounding pharmacy.
After I knew LDN worked well for me, I researched online how to mix Naltrexone tablets with water, and kind of based my procedure off what I read. Most instructions say to use distilled water, but I don't.
I then approached my primary care doctor (Kaiser Permanente) and asked if he would prescribe the 50mg Naltrexone. He already knew it was working for me, and seemed to think my water mixing procedure was reasonable.
I get twenty 50mg tablets mailed to me at a time (roughly a 3 month supply), covered by insurance. The pill bottle actually says "Take 1 tablet by mouth every 5 days", which, of course, is NOT how I take it.
Hope you can get the Naltrexone covered by insurance. If not, just buying 50mg tablets will save money compared to a compounding pharmacy.
PS: Once you find a bottle the right size, it's really easy. Just fill with water and drop the tablets in. Shake and put in the fridge. You might search Amazon.com for "80ml bottle" or whatever bottle size is right for you.
