I first had psoriasis on my elbows about 20 years ago and it got worse and worse. Five years ago it had got to it's worst level with large patches on my legs and torso. My fingernails and toenails were disasters and looked terrible. I tried various creams both OTC and prescription and they provided temporary relief, but it was a constant battle. Since then I stumbled onto two things which I think possibly made a significant impact, but I can't be sure. Regardless, it's gone now and the patches on my legs and torso are gone. My nails are all clear also. I believe the first major break through was a CPAP machine. I had severe sleep apnea and 4 months after being on CPAP there were major improvements, but it wasn't completely gone. I'm not 100% sure it was the CPAP, but nothing else changed and their is some research linking sleep apnea to psoriasis. Body patches disappeared, but I still had some on my lower legs. My fingernails cleared up for the most part but, my toenails were still ugly. I think the second breakthrough was a homemade drink I added to my diet twice a week. Three months later I was clear. That was two months ago. I'd like to find out if my homemade elixir has the same impact on another person. I'm not selling it, but I'll share the recipe. Just would like to do it with someone privately to verify results first before suggesting it to everyone.
