Hey there, I would take it easy with the Red Bull, there is tons of caffeine and I know that I can easily get a tummy ache from one of those things and I am not pregnant…if you are having a hard time with energy or waking up you could try drinking more fresh juice, 100% not the juice cocktails, taking a shower first thing when you wake up, eating more cold foods like sandwiches, fresh veggies cut up, anything crunchy…talk to your doctor about more suggestions but I would lay off the red bull till baby is here!! It is always better safe than sorry, Love Meg
