i'm still at the hospital, feeling extremely flabby..

it's 5PM and they just finished handing me over my bills, mc, discharge documents and medications. lucky i waited till late to have a shower or I would've gotten pissed waiting. i put on normal clothes today after 30 days of wearing those baggy green hospital clothes, and realized how flabby i've gotten. I only gained a net of 0.5 kg throughout my stay here, but how could i have gotten so flabby? this calls for serious exercise when i get home, and as discussed with Najah just now, perhaps a cup of coffee to get all the excess water out a.s.a.p.! Or else all my hopes of learning to cook will fly off the window...help!!
