I have been suffering from depression for over 4 years now and one thing that really bothers me about it is that I cannot laugh normally; I can watch the funniest videos and only get a slight chuckle out of them whereas others might complain about dying from laughter. I'm also extremely unmotivated, have no libido, and I have to sleep for more than 12 hours everyday. Anyway, I have noticed that the longer I stay up at night, the better I can laugh at funny things, but not as much as this one time when I stayed up late and took cold medicine.
I remember this one night in the winter of 2011/2012 I was really sick and had to take cold medicine for it. It was late at night and I had to sleep so I took Benlyin All-In-One Cold & Flu Nightime Syrup and I watched this video on YouTube and I laughed really hard at it. I couldn't remember the last time I laughed as hard as I did when I watched that video. It's like someone turned up the intensity of my laughter from almost 1 to 7 on a scale of 1-10. I want to be like this everyday. I want to be able to laugh like normal people do. It's really frustrating when you want to be able to laugh, but nothing can make you laugh. It feels like you've been robbed of your emotions.
Now obviously I can't take the medicine everyday, but I was wondering if there is something that I can take everyday that will produce similar results to the syrup. One of the ingredients in the syrup is Chlorpheniramine which is an SNRI. Could this have been the cause of the enhanced laughter?
