17 days is quite an accomplishment, and I reiterate what NH has said, so well done.
The vital thing now is how you refeed and with what, so be careful only to do so with fresh and preferably organic produce, and build up your nutrition slowly: respond only to appetite and take at least the next 17 days in recuperating.
I would strongly recommend you supplement with organic sulfur crystals/flakes, after one week of refeeding, building up to two dessert-spoonfuls twice a day in juice on an empty stomach. Make sure it is thoroughly dissolved................... http://www.naturalnews.com/029263_sulfur_joint_health.html
