It sounds like depression. Although again it could be a question of meds. I take both anti-psychotics and anti-depressants not to mention anti-anxiety medication as well. It makes me a little tired during the day and I don't have as much energy as I used to but then I'm getting older too - closer to the wrong side of 40 all the time now

Talk to your doctor - mine does all he can to keep me out of hospital so you never know others may be the same.
