hello, I'm almost 6 weeks post op, I had my surgery on 01\08\2018 I'm having some concerns & questions if you could help me. I'm having trouble drinking 2 liters of water a day when I try my best I only drink 1.5 liters. and sometimes I put a normal to small sized portion of food on my plate and spend an hour, maybe 2, to finish it. is that okay or should I put smaller portion? the last concern I have is, we don't have any gym near my area so what could I do instead? plus I don't really have the time because I'm a medical student and have a part-time job. I'm terrified of having loose skin. Thank you.
