I am also with the THG and am exactly 4 weeks post-op today. I had my first phone call from the dietician this morning and ive got to say it was very informative. I dont really feel like i would have got any more info by being face to face. THG are actually updating their info so i didnt know alot of the the stuff she said ~ for example she said that we can drink anytime and dont have to wait before or after meals( Yaay!) She emailed me all the info following the call which will prob become my bible!!
As for fills i guess everyone is different ,like I said im exactly 4 weeks and mine is next week but i feel that i probably need one sooner as i have no restriction. It may be different for you, im sure if you feel you dont need one they wont do it. You may even be able to change the appointment date. The new info also says you only need to be on liquids and mush for 24 hours each.
Hope this helps xx
