i1BB
I am a tea lover but i never take any tea (western/ chinese) when I start my first IVF procedure. Actually, I consulted a Tea Specialist at Shanghai (cos I went there to buy some high quality tea leaves) the lady told me there is no concern. However to play safe, I cut it off totally. I only drink warm water and friso milk once a day. Occassionally, I drink milo, horlick and also oat.
I think at coffee bean got vanilla drink which you can order. Shouldn't be any issue. Ever since i ttc, i cut down a lot of stuff including my favourite food like sashimi, seafood, asam laksa, cold drinks, alcohol (social drinker) etc.
