When using the technique of bed restriction, should I go to bed later or get out of bed earlier? Does it matter at all? Currently I go to bed at around midnight, so reducing my time in bed by going to bed later, it would be around 2am, which seems quite late to me. I am a night person, so I would be glad to be allowed to go bed later, while improving my sleep quality, but I'm not sure if a too late bedtime will diminish sleep quality?
