i do not want to alarm you, (((pegasus))), but i really would urge you to see your doctor as soon as you can. unexplained tiredness and weight loss against a background of stable/increased food consumption = not a good combination.

it may well turn out that because you are overworking that you are tired, eating more, burning more energy etc. but if i lived anywhere near you i would march you over to a doctor, pronto! let them decide what's what .
