What's a good excuse for not drinking during the TWW??

Most social events I go after work or on the weekends involve cocktails or grabbing a pint with friends. 🍻🍸🥂 I am happy to abstain from alcohol during this time but I don't want to make a big deal about it! If I don't have a drink while out with the girls they will inevitably ask if I'm pregnant and I don't feel like answering a lot of questions about where I'm at in 'the process'. I prefer to keep that between very close friends, I'll tell them news if I have any. But since I usually have a cocktail it will be SO obvious if I don't drink and I don't want to be a hermit for the next few weeks. Any other ladies out there have the same fears?? Any good excuses that are believable?? 😂 #firstworldproblems
