About once or twice a year I get horrendous ott face stuffing hunger the day before my period is due.I haven't had this for about a year but its back and seems to coincide with worse other symptoms too as my boobs are killing(sorry if tmi) and i am exhausted.I have eaten 3 kitkats and 2 packets of crisps and no decent food today at all and could eat more tbh.How can i stop this
