Non-packet brands of artificial sweetener?

[Hal65]

In Pattaya I've been able to find packet sweetener where 4 calories/1 g is equal to 2 tablespoons sugar (1% sucralose). I've also been enables to find big bags of half calorie sugar, (0.2% sucralose).

What I really want is a big, unpacketed bag of the 1% sucralose or equivalent artificial sweetener. Has anyone found a good source for this?

In researching this I found out you can buy pure sucralose from China for a very good price. It's 600 times stronger than sugar so a matchhead worth will sweeten up most anything.
