It's a challenge at times, especially at first. Relearning how to drink...slowly and in sips; how to eat...slowly, in tiny bites with a lot of chewing; "Sip, Sip, Sip, Protien, Protein, Protein!!!" is the motto for the this entire time.
Relationships change drastically...not only with the mirror and your own self image but also your relationship with food...you really have to stare in the face of why you overeat; dynamics between you and family and friends will change too. I was always the fat and jolly one...now I am real and myself...sometimes I am jolly sometimes not. Everyone had to adjust to that and I lost some friends over it all.
If you do as you're told by doctors and nutritionists (NUTs they call them here

) and if you find a good counselor, all will turn out...better then you could ever dream. I recommend counseling before and afterward...saved me in many ways...from self-sabotage or cross-addiction.
There were a lot changes really...not just to my waist line....I could be here for days writing about them!

Just stick around here, people who are dealing with all these things and so much more will be here talking about them all.
Good that you are asking the big questions and this one IS HUGE...would take me days to convey all the detailed changes but I gave you a general overview...very very general!
Oh and come here for the TONS AND TONS of support offered by the kind and wonderful people here!
