Study Description
Brief Summary:

Efavirenz causes neuropsychiatric side effects and sleep disturbance, including vivid dreams, dizziness, and abnormal tiredness. These symptoms are frequent during the first weeks of treatment, with subsequent attenuation but may not completely resolve even years after efavirenz initiation.

The investigators plan a twelve week, randomized, placebo-controlled, double-blind study. In group 1, efavirenz will be replaced with efavirenz placebo plus etravirine, in group 2, efavirenz would be continued, and etravirine placebo given in addition. After six weeks, patients in group 1 would switch to the regimen of group 2, and vice versa.

The primary endpoint of the trial will be patient preference. Sleep quality, daytime sleepiness, and anxiety will also be investigated.
