is diet really important?

Im so bad at keeping a diet i think im actually addicted to chocolate litterally, if i go without eating it i feel suicidal as well as being uncontrolably smelly from fecal Body Odor due to leaky gut...
what im getting at is, can i still eat the occasional piece of chocolate? and some caffeine daily? im sorry if i sound like a fool and that chocolate and coffee is on the hell no list. but this candida has got me craving chocolate so bad im am going to say im highly addicted, and if i am to stop eating chocolate it would have to be swapped with caffeine(daily), if i sound like a dill tell me, im no expert on lgs.. any help would be really good. ALSO if anyone with Sugar cravings knows an natural appetite suppressant that works(not hoodia) please let me know :)
