BG - I forgot you had a 3ww...that must be torture & I though 2 would be bad!

This is going to sound silly but since this is the first time I have officially been in the TWW I wanted to know a few things...

Has anyone changed your diets at all over this time...e.g. I usually have a coffee & tea at work & I wanted to know if this is something that is safer to cut out all together? Are there foods that ppl are avoiding during this time?

I know that they stay to try & avoid strenuous exercise (which is okay cause I avoid that now anyway) but is there anything else I should be careful of??

Your thoughts on this would really help!

I guess I just want to give myself the best chance of a BFP. Every little bit helps.
