Before you fast n sleep that night perhaps you can have a little supper.
Within 5mins, you can time yourself, sip a little by little first then finish it all.
Listen to music, or read magazine/books. Try not to think about the taste. The more you think, you will feel like vomit.
To me, it really felt like redbull that strong. I felt sugar rush. as if like “ finally I can drink sugary drinks “ 😅
