Energy drinks

ks

I know energy drinks have a really bad rep and I only have one when I need the boost of caffeine. I get up at 1 am tomorrow morning for work, I never take shifts this early. I want an energy drink to give me an energy kick. It has 200 mg of caffeine which is the daily limit as told by my doctor. This should be fine right? Would it effect the baby given that much caffeine at once? Would like to hear some input. I’m in my second trimester.
