I wrote post op but meant pre op! 
Minimum I eat once a day, normally, twice a day though. Usually fromage frais or a slice of cold meat for lunch and then a random dinner. Only once have I eaten 4 meals in one day since the op and I was disgusted with myself! 
Drinks wise, today has been the worst day since coming home from hospital. Best being over 1.5l fluid in one day. 
Only meal today I had around 5ish and dumped on it (ugh, first time dumping, not very nice!) I think im hungry. Kinda got used to hunger pains and learnt to ignore them but will get some grub anyway and see how I feel afterwards
