No worries Fretboard,
If you have 4 weeks Undetected, that is the holy grail bro! You are undetected and will still treat for another 8 weeks? That is the overkill factor that locks in the cure dude. Make sure you do 12 weeks, or even 16 (or 20)! If insurance cuts you off at 8 weeks, keep taking your Generic meds for another 4 or 8 weeks.
Personally, I would take the 20 weeks if you can, since you had some fibrosis, and have the meds. Unless you are having issues, it can only help your chances. The longer you treat, the better your chances (up to 24 weeks) You are on schedule for a cure!
I did 6 weeks (UND), then EOT (UND) and now SVR 16 (UND). The early UND is key, 4 weeks it is looking good for you!
