Louisa,

the first months on this WOE you should be prepared for some hormone battles. There are many positive effects of this WOE (lack of PMS, no cramps, no bloating, no panic hunger for sweets etc) but we can also experience some bad things. It can be anything - nothing is like it used to be. Hormones are stored in fat and losing fat tissue will release them.
Personally I've reached balance in month 4 but It could come later or hopefully - earlier.
Just take care of yourself and remember - things will regulate themselves! I hope for those positive effects for you.
All the best!
Alina
