Hi there - unsure where you got 2 years from and the ability to reverse it with alternative therapies ?  there isn't a set period for the honeymoon, some may experience a few months, some may not even get this.
If you're newly diagnosed ? then I can appreciate the question, however sadly once type 1 has been diagnosed there isn't any way back from this, I also questioned my diagnosis thinking I could do something to try to prevent full onset but it is inevitable sadly.  The best way to look after yourself is to keep your levels as stable as possible, be vigilant with your control, it is suspected you can prolong the honeymoon phase if you maintain good control, I was told this by a t1d consultant, also just learn as much as you can and become a t1d expert, best wishes J
