Brief Summary:
The purpose of this study is to evaluate how often patients with hepatitis C infection have abnormalities of sugar and fat utilization. Additionally we would like to find out if these abnormalities of sugar and fat utilization are common in other liver diseases, or related to being overweight.

Arm Intervention/treatment
No Intervention: 2
One half of the patients will take not medication for 30 days and then have labs redrawn
Experimental: 1
one half of the patients with insulin resistance will take 4ml of 20% N-acetylcysteine BID for 30 days
Drug: N-acetylcysteine 20% 4ml
N-acetylcysteine 20% 4ml
Drug: N-acetylcysteine 20% in 4 ml
N-acetylcysteine 20% in 4 ml

Primary Outcome Measures :
  1. Those patients who are identified to have insulin resistance will be asked to participate in the treatment phase of the study [ Time Frame: 2 years ]

Secondary Outcome Measures :
  1. One half of patients with insulin resistance will undergo 30 day treatment with N-acetylcysteine to see if we can measure an improvement in fasting insulin and glucose levels [ Time Frame: 2 years ]
