I haven't found this but just wanted to say that it really annoys me when people feel they have to attribute your/my grumpiness to a particular thing! I think everyone is entitled to be grumpy for no particular reason every so often; in fact I think it's quite healthy.
Sometimes I do have to tell my husband to stop asking me what's wrong - I'm just feeling irritable. No it's not my TOTM, I don't feel ill, it's not the diet, I'm not tired, no he hasn't annoyed me, I just feel grumpy!
Anyhow - rant over! hope you're feeling less out of sorts soon.
