answer:I use caffeine to fight depression. Sometimes I do go overboard and make myself anxious, though! Unless I’m really droopy and desperate before something important at work, I refrain from any coffee outside my 1–2 cups in the morning. I do, however, drink tea (black and green) and diet soda throughout the day. If I’ve really gotten myself in a bad way, to where my heart is racing or I get short of breath, I’ll drink some calming herbal tea like mint, licorice, chamomile or valerian.
