I've discovered that one of the managers at work takes Prozac on a regular basis to maintain some kind of level thinking. Another one drinks tons of highly caffeinated beverages, to which she add several packets of sugar.
I've noticed that some workers eat a ton of food on their break. Others eat a lot of sweets.
None of these people would probably be considered as needing drug treatment, but it's obvious that although they aren't taking illegal drugs, their personal "drug of choice" is either legal or it's food. We all probably overindulge from time to time. However, even using food to somehow dull the senses still doesn't seem right. Certainly, it can lead to health issues.
The better way would be to step back and take some deep breaths. Maybe meditate on Scripture verses or think peaceful thoughts. Doing something other than putting too much food, too much caffeine, or too much Prozac into your body would be more beneficial in the long run.
What's your "drug of choice"?
