I dunno, but this is only the 3rd cycle on the increase. Will hold out a few more cycles before I do anything.
EDIT= Of course it has been colder the last 2 days! Below freezing at night. I had the thermostat at 70, moved it up to 73 tonight, which is much warmer than I would like, but hope it'll make him feel better. I'll be sleeping without the covers for sure! :evil: At 70, I had to drag out a tiny fan for my face last night, will certainly need it now. I feel comfortable until I get in bed and then it's too much covers.
