Coffee and pregnancy

I am a lover of coffee. Before becoming pregnant it was not uncommon for me to have 3-4 cups throughout the day every day. During my last pregnancy I stayed away from coffee during my first trimester and had an occasional cup here and there during the rest of my pregnancy.

Cut to now: I have a 16 month old son who is teething and a complete nightmare at night and most days I’m struggling to stay awake by 5pm. I’m just now 5 weeks and I have stayed away from coffee ever since I found out but I am STRUGGLING to keep it together without my coffee! Any ladies out there still drinking coffee or have any alternatives to keeping your energy up?
