May I add?
the only way to alleviate sleep loss is to get good sleep (ie make sure there are
no causes of sleep disorders such as RLS, apnea, GERD etc), regular sleep hours
(approx same bed/wake time, every night)  and an adequate amount of sleep (8-9
hours every night) for life...  (something that the original poster has not and
does not seem prepared to do)
