Does anyone have any tips for getting more energy through the day. My lung function is in the 80s/3.0 and I run 3 miles about 3 times a week. That helps a little for some extra energy but most of the time its hard to make myself get up and do the things that need to get done. I get so lazy sometimes. Why does this happen to cfers? Is it because of the lower then normal lung function? I try coffee and green tea but it doesnt do too much!
