I'll make this short. Since the age of 13 I've had major cognitive and emotional issues (ADD, OCD, panic disorder, agoraphobia, clinical depression, social anxiety) that had gotten worse throughout my years. Over the years I've tried everything from CES to light and sound to tDCS and also countless botanicals and several nootropics. Decided to give CBD (cannabidiol) a shot this past weekend. I knew that there's virtually no toxicity to CBD and I've read that it can be very fast acting, so I did about 3 times the recommended dose (500mg) on Saturday and Sunday. It's working like I never expected. I feel my cognitive issues are disappearing and subsequently my depression/anxiety is nearly undetectable. I won't disclose what brand I'm using, since I don't want to be labeled as someone who is promoting this company. Anyway, it's quite expensive - $175 (500mg) for a bottle just over 3oz. (they also sell 1 oz bottles). or you can buy a version that is 10x stronger for $275 (3oz bottle). I've found that once levels are at a sufficient level, then you can use less per day. I'm estimating that the high dose CBD (5000mg) in a 3oz bottle should last 3 months or longer and that's using it daily.
