Weird I don't even know what happy pills are yet I always use those words to refer to someone who makes me smile. If we are going to take these words seriously, it doesn't really bring good results. Your happy hormones which is scheduled to be released sparingly so you will have enough until your dying years, is being squeezed out dry just to give you all these temporary euphoria. Mood altering substances must be avoided sometimes. This includes that person you are maybe infatuated with.
Wounds and infections should be seen and treated by a healthcare professional.
