Hi all, I'm sure this is covered elsewhere, so forgive me for asking if that's the case - but is it normal to experience mood swings while on LL? I'm only on day 9, and have noticed that I can change from being totally euphoric one minute, to ratty as hell the next - often for no apparent reason. It only seems to happen in the evenings - I've been feeling great during the daytime. Now, it has to be said that I've always been a bit of an emotional sort but this is definitely worse than usual. I snap out of the rattyness as quickly as I snap in to it, so I'm not hugely worried about it, but just wondered if it was a common "side-efffect", and if so, does it last long? Many thanks!
