I'm not proud to say it but I've been taking an SSRI for about 7 years, I would say I am addicted. I also think I was just born with less serotonin or whatever that the average person. Ive just been a bit more withdrawn and melancholy than most people all my life. It works though and I have no side effects and I am by no means emotionless or happy all the time but I just dont like to be dependent on anything. I've lowered my dose and tried to lower it again twice and I just spend the following months in a darker cloud. So on it I stay so far.
With what your talking about CBD might be of help. I spoke with a couple vets over a beer a couple weeks ago and at least one is finding relief with CBD. I dont know much about it, I am curious though. You come across people that think marijuana is a cure-all but I think there are real ways in which Marry Jane can benefit people. CBD It will not make you "high" I just grabbed this from youtube https://www.youtube.com/watch?v=VZihJxD1UQQ
