Study Arms:
- CBTi (Type: EXPERIMENTAL): CBTi is a multicomponent treatment that seeks to teach patients about sleep and the factors that affect sleep as well as to work with the patient toward altering sleep habits to increase sleep propensity and regularity. Specifically, participants will receive 8 weekly individual sessions of CBTi according to the VA CBTi protocol. The investigators will follow the semi-structured approach to treatment described in the VA CBTi protocol, which allows the case conceptualization to drive the order in which treatment components are introduced.
- Monitor Only (Type: NO_INTERVENTION): Study participants who are randomized to the Monitor Only (MO) control group will be followed for 8 weeks of usual care (i.e., they will be advised to continue doing whatever they were doing to manage their GWI and insomnia symptoms without change dosage or frequency of treatment). Participants randomized to the Monitor Only condition will have the option of receiving CBTi delivered by telephone, at no cost to them, upon completion of post-study procedures.

Based on this trial design, predict the completion outcome and termination type (if applicable).
