caffeine content


Caffeine in Chocolate
Ghirardelli  72% Cacao Twilight Delight: 22mg per 17g square 
Ghirardelli  86% Cacao Midnight Reverie: 20mg per 13g square
dark chocolate in general is 28 mg per 1.4oz (40g)
1 oz (28 g) Cadbury (small) bar  is 15mg
milk chocolate in general 3-10 mg per 1.4 oz (40g)


Caffeine in Tea
Black Tea: 23 - 110 mg Oolong Tea: 12 - 55 mg Green Tea: 8 - 36 mg White Tea: 6 – 25 mg

Drink green, white and lightly oxidized oolong teas are good choices, as they tend to benefit from lower water temperatures and shorter steeping times.


Guidelines
Adverse effects have been reported when pregnant women consume more than 200mg a day.

I aim to have less than 100mg a day, which would be:
 - 1 green tea and two Ghiradelli squares
 - three Ghiradelli squares
