Deep sleep for three days

Hi guys I have had three days perfect deep sleep this is the first time after quitting propecia 2.5 month ago I have a deep restoration sleep but after that things are drifting towards pfs baseline although still decent sleep I have noticed after quitting pfs I have vomiting once month and after that my sleep get better for three days than it get worse again
