I would look for the tablets in a health food shop too or see a naturopath.

I've just started drinking the tea and have got the leaves. I brew them for 8-10 minutes because I think it gives a nicer flavour than the recommended 5 minutes. I started drinking tea last week (approx 34/5 weeks). I'm drinking 3 cups a day and will probably try and squeeze in more over the next few weeks.
