I started on Nystatin powder from a compounding lab a week ago. Wow the die off, itch and burn symptoms have been uncomfortable. With all the good testimonies I have read about Nystatin and my docs recommendation, I am trying Nystatin. I natural antifungals for over 35 years. I am still taking my Threelac daily and have for 6 years. It is just not strong enough for me. I am also taking phyllium/ Bentonite to get rid of the toxins from the die off. How long until this lousy feeling goes away? Thanks for you input. It has been an encouragement.
