Some people may have their candida come back as it is not the root problem...and in some cases the root problem may have to do with the lymphatic system which is responsibly for getting rid of the alot of the toxins in your body...the best way to make sure your lymphatic system is working correctly is to get a rebounder and use it daily as gravity will work on all the lymph system..also massaging towards the heart to help speed up circulation..
Just starting on my own journey with candida...believe I have it systemically for years also, I understand what you've been through..hope this helps! (Large doses of vitamin C caused me to have the drunk symptoms due to die off of candida...I don't think it's the diflucan)
