hiya.. firstly welcome to ob!
Yeah for TTC! Its and exciting journey and I hope yours is short!
Plenty of women (though I am not one of them) mix study with children, in fact Uni's have creches so you can leave them there!
As for alcohol, thats purely personal choice but a few wines now and then in the 2ww wont do you or baby any harm really... as the baby isnt feeding off you yet
Good luck!!!!
