Hi Stefano...I hope you wont mind me saying so, but your thinking on candida is sadly lacking. If you think that taking nystatin or diflucan will cure systemic candida condition then I'm afraid you are dreaming. And if you believe that antibiotics will help to cure your candida issues then this really shows your lack of knowledge concerning candida and how it behaves as a pathogen. If you take antibiotics over any length of time you will simply encourage candida's growth and spread. Read this.
If you really want to cure your candida then you will have to work harder and do it yourself because doctors are so clueless about candida. That means that you must make every effort to learn all about how candida behaves as a pathogen. You need to do this in order to formulate a successful strategy against candida. You will only be able to defeat systemic candida using an accurate strategy based on its unique behaviour. Candida is difficult to cure and will be incurable unless you have considerable understanding about its behaviour.
To kick off your understanding about candida, I would read all of my candida blog posts shown here. This will open your eyes and show you what you are up against. Then I would also expect you to do your own research on candida to validate everything that you have read. What's more you will never cure your candida issues if you cling to easy convenience and blind short-cuts. You will need a fiercely targeted multi-protocol approach to eliminate your candida. You will not cure your condition by just taking two pills in the morning and two pills in the evening. Convenience never cures anything.
I had candida 10 years ago and got rid of my systemic candida by first intensely studying candida then devising a multi-protocol strategy that directly attacked all its behaviours. I managed to completely cure myself of this disease and my candida has not returned in 10 years.
