Thank you everyone. You are right - I just don't eat enough. I logged my calories on fitday today for the last week - best as I could remember - and although I feel like I never stop eating - I'm not making 1800 cal on any day.

So I have planned out eating for the next week to get me to 2000/day & Ive bought a frame bag to pack more food into so I can take some peanut butter & jam sandwiches. I also bought an electrolyte sachet to try. www.peakfuel.co.nz We don't seem to have the Lara or Clif bars here at either the health food shop or the cycle shop. So will try real food for a while longer. Maybe I'll get a ride in on Wednesday afternoon if I can arrange a babysitter!

I couldn't help myself & also brought home a pair of arm warmers. I rationalised that I'd need them to be able to wear my cute new vello bella jersey from TE shop. It's for my birthday in 3 weeks, but has already arrived & I know where my husband "hides" things.
