i've been getting terrible heartburn lately and it seems that I get it after drinking tea

i have a small cup of coffee in the morning. not even a full 8 oz worth

then i'll have a big cup of green tea and i'm fine

but when i have tea after lunch at work or in the evenings i get terrible heartburn

i looked online and found that tea often helps heart burn

anyone else get this? i ususally drink green tea or ginger tea

weird!! and i really like my tea especially now thats its cold out

anyone else?
