Crystal Light Equivalent or Substitute for Non-US swayers?

Hi Not sure if this is the right forum but I've seen lots about Crystal Light Drink for TTC a girl as part of the diet. I am in Australia so have no idea what this is. Can anyone enlighten me on a substitute or equivalent drink? Thanks!

you are looking for drinks with aspertame in them.  Someone told me Tang has it.  Aspertame is also called  including Equal, or NutraSweet,

 We can get Crystal Light here through a US food importer, it is expensive though.

If you live in Melbourne you can go to the shop, otherwise they do mail order. Some people have also bought it from Ebay. I found that Tang does have some Aspertame in it but it's also packed with sugar so if you can get the CL it is better
