Need help on HCG diet

Just been given info on HCG diet from a naturopath - have read the booklet - but have a few questions.  Firstly those who have reached their goal weight - have you kept it off and if so for how long.
Also i could not see anywhere in the booklet about people on medication - it says you can only have asprin - I am on anti depressants - has anyone been in this situation and what did you do?
I eat because I like food - and I live alone and so wonder how I would go on the 500 calories even if I am NOT hungry.  Anyone else like this?  
Just finding my way around this forum so hope I have done this correctly.  Thanks.
