Otc meds are not specifically for one person. Anyone can buy them as they are considered safe by the fda. Prescription meds are only used under a doctor's care to treat a specific person's needs.
The FDA regulates OTC drugs by using monographs.....its like a drug recipe book that shows the safe dosage and ingredients.
Setting your own goals gives yourself a reason to have good feelings about yourself. by being worried about something of your own, it can become more positive for you.
