Vitiligo treatment with Oral mini-pulse therapy

Hello, I have had vitiligo for almost 2 years. It is still MILD in nature but growing slowly.I have tried many treatments but nothing seems to HALT the progress. Recently I found a treatment- Oral mini-pulse therapy with betamethasone/dexamethasone, check here - http://www.ncbi.nlm.nih.gov/pubmed/8225724 #
and also this- http://onlinelibrary.wiley.com/doi/10.1046 /j.1365-4362.1999.00623.x/abstract

My GPs are not innovative in treatment, they dont know the varieties of treatment. So I think I will try myself. Can anybody help me with the above treatment pls.
I m dying inside. I just need to halt the progress at the moment.
Plssss help
