But some 'detox tea', not a weight loss tea, one that has fennel, milk thistle, dandelion, licorice root, nettle, lemon, ginger or any combination of the above. Nothing with caffeine or chemical names listed. Only botanical names and/or common names.
Drink lots of it.
Drink lots of water.
No caffeine, no processed food, no sugar. No tea, only herbal tea, at least for the first few days.
Stick to fruit and veg, mostly raw for a day, max 2 days, then shift onto wholegrains, legumes etc. and shift slowly back onto your regular diet.
