  1. FIQ, Fibromyalgia Impact Questionnaire; SF-36, Short Form-36 Health Survey. aAlcohol consumption levels were defined as follows: none, 0 drinks/wk; low, ≤3 drinks/wk; moderate, >3 to 7 drinks/wk; heavy, >7 drinks/wk. bTukey HSD method was used to perform pairwise comparisons of least-squares means between groups from a multivariate model that adjusted for age, employment status, education level, body mass index and opioid use. P-values <0.05 were considered statistically significant.
