you write that as if it was strange to sleep with a watch on, and always charge the lume before you turn the lights off, and set an alarm so you can check the lume at intervals through the night, whats wrong with that?
@ OP your watch needs at the least regulating by a competent watch smith, best is to check for the olde watch smiths shope local to you and ask there if they have experience with a 2836 and would they work on a well made replica? DO NOT GO IN TO AN AUTHORIZED DISTRIBUTOR, like goldsmiths ect
