in winter i have my thermostat turned down to 58 at night. and about 63 during the day. daisy and i use more blankets and wear sweaters at night. in the summer i so seldom use the a/c. it might come on for a few hours in the late afternoon. if i have asthma problems i'll turn it on a bit more often. it's been a while since i've used my nebulizer. i think i better go look for it in case i need it. my nook goes everywhere with me. just in case i have to wait anywhere. don't think i'll be looking for another one til this one stops working. i only use my dishwasher every 7 to 10 days. finally it's just me and daisy back in my home and we're back to not using the dishwasher much. take care,
