Interventions

This randomised double-blind, placebo-controlled study will examine the efficacy of modafinil to counteract possible daytime sleepiness after CPAP withdrawal in long-term CPAP users. Subjects will be given an 'Autoset' CPAP machine to take home to assess their CPAP compliance and subjects will also be given an Actiwatch to assess sleep-wake activity for 7 days. Subjects will then report to the laboratory where they will undergo overnight polysomnographies using CPAP for two nights and then for t

This randomised double-blind, placebo-controlled study will examine the efficacy of modafinil to counteract possible daytime sleepiness after CPAP withdrawal in long-term CPAP users. Subjects will be given an 'Autoset' CPAP machine to take home to assess their CPAP compliance and subjects will also be given an Actiwatch to assess sleep-wake activity for 7 days. Subjects will then report to the laboratory where they will undergo overnight polysomnographies using CPAP for two nights and then for two nights without using CPAP. During the waking hours subjects will complete a variety of neurocognitive tasks and questionniares. After a washout period of 28 days, subjects will repeat the protocol, receiving the other study medication.
