1970,
You would be better off having a pint of lager than a pint of normal lemonade!!.
On Sunday, I went for a carvery with my missus (Meat and non root veg only). At the end of the meal, I had been drinking pints of tap water. She left a glass of diet coke, so I decided to knock it back. On downing it, I suspected that it wasnt the diet variety. When we arrived back home, I did a one hour test expecting a slightly higher reading due to the high veg intake, but my reading was much higher than expected!!. It must have been full blown coke!!.
In future I will ask to see the bottle, but in the meantime, I would give the full blown lemonade a wide berth if I were you!!.
Steve.
