There is no "sleep" button since this is no skill.
(In real life, maybe, but not in this game <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" /> )
You can use teleporter stones for instantly travelling to your favourite bed, or make one out of hay (tip : carrying hay with you and combine it only at the desiredplace for sleeping <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" /> ) .
Also, there is the "transportable bed" ... <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
Have you put a skill point into the skill "identify" ?
