I didnt... thought I would when we first planned to TTC...But I think TTC is hard enough without worrying about not drinking tea/ and wine etc. After only 2 weeks of TTC, i could see my chances of having a glass of wine ticking away in front of my eyes.... Night before I took the test I made a point of having a large drink - quite ashamed now! but thought it was my last chance!
I avoid caffeine - not religiously, I might have a couple of cups of tea or coffee a week - more because of my miscarriages than for ttc. I traditionally indulge in a large glass of wine (or two) the 'celebrate' the arrival of my period
