Notts Boy,
You defo need more water -- read this link I found in the Cambridge Diet forum:
http://www.minimins.com/cambridge-diet-forum/19842-why-drink-water-vlcd.html
Temporary solutions for headaches:
* paracetemol
* Lempsip Sinus 12 hr (also known as Lemsip Flu 12 hr)**
**The additional ingredient in these tablets helps me enormously with stress headaches.
I was told by my GP once that limiting calories to less than 1,000 a day might cause the body to be in "stress" mode and why my sinus problem / sinus headaches could be worse doing something like this.
However, having said that I personally only had a bad headache on Day 1 of Lighter Life and since then have been fine -- but have got into the knack of drinking 4 litres a day.
Between 6 am and 8 am I sip 1 litre before work, then 1 litre before "lunch" time (which is now WALKING time for me) and 1 litre after lunchbreak .... and 1 litre when I get home.
Also, I don't use a litre bottle as it looks daunting -- I use 2 x half litre bottles and take lots of sips and find I've soon finished one bottle and am onto the next one.
Best wishes with LL, with your water intake + solving the headaches.
regards,
sharon
