Hmmm, looks like everyone has a different answer to this one. I use 1/2 a lemon in 16 oz of hot water, then do the same with the other half and hour or two later.
On True Lemon and True Lime- I LOVE these products. Both of them for fantastic for cooking. The lime powder is really great in taco seasoning, homemade salsa, fajitas, carne asada, etc. The lemon is fantastic in hot water or tea, on chicken, fish, and pork chops, and in home made tartar sauce. Last night my 4 year old coughed all night long, despite having her medicine. Finally, I mixed some lemon powder with hot water and honey. She drank it really well, and it coated her throat and stopped the cough. One last idea with the lemon or the lime powder would be to mix it with diet sprite and vodka to make a yummy lemon drop type drink.

So, yes, the lemon water really does work.
Definitely will be trying hot lemon water . . . thanks, gang.
