Week 3 now and lost 20 pounds in 21 days :O) All going great but I keep forgetting to drink enough water - my only problem now is my knee joints have suddenly started aching over the last 2 days, so much so it is making it hard to sleep, it is like a dull throbbing - it may be uric acid build-up do you think? I will defo drink at least 8 glasses a day from now on - I also take 2 splenda tablets in my coffee with cream, about 2-3 mugs a day, so 6 splenda tablets, I wd really rather not take splenda at all, as it is said to cause joint aches in some people, plus God knows what else it is doing to me ref brain toxicity - but I crave a sweet taste in my coffee - any other healthy sweeteners out there? Lastly i hear joint aches could be due to low potassium? Any thoughts on sorting this out wd be greatly appreciated - the diet/change of eating has been a breeze, no hunger at all - 20 pounds in 3 weeks is great, and that with no exercise, just bought a bike so will be on that most days, be interesting to see how the losses continue :O)))
