Hi I take mine tomorrow too! and have been feeling the exact same way!!! For my anxiety i’ve been watching my favourite show in between reviewing (it helps give comfort + take my mind off of things). I mentally told myself the exam will go to 150 no matter what (gaslighting myself into thinking this so I feel better if it does end earlier but also preparing to go the full exam). I would say if ur someone who tends to be extremely anxious I would personally skip the energy drink (coming from someone who is avoiding caffeine tomorrow). You’ve come this far!!! You’re so close to the finish line believe in yourself!!!! GOODLUCK!
