It's sub-zero outside, so I've kept the windows shut, and the air in my room feels particularly heavy and stuffy... I suddenly looked in the mirror one night, and I realized my face has become round like the full moon, probably from overeating tangerines and bungeoppang (fish-shaped bread) all winter. Is it just me who feels a chill in my heart? I've been busy with gatherings, caught up in the holiday spirit, and I've been using the cold as an excuse to stay still, and my body has become really heavy. I've decided it's time to stop procrastinating and start taking care of myself, so I've been looking into diet shakes. I've had bad memories of forcing myself to drink unpalatable drinks, so I'm a bit hesitant about choosing, but I've heard there are a lot of diet shakes out there these days that taste good and have good ingredients. Is there anyone out there who, like me, drinks diet shakes to satisfy their nightly hunger? I'm curious if there are any that aren't overly sweet, yet have a subtle, nutty flavor like grains that won't tire you out. Even though the air is stuffy, I long to feel lighter in the middle of the night. Could you share your precious diet shake reviews? Are they delicious enough to drink with just water, or do you need to mix them with something like soy milk? Could you please advise?
