Thank you for your responses Visual and Dukkha.
Visual - I have been taking 1.5 mg (0.5 x 3) a day for nearly 5 years now. I have also been taking effexor for 6 years for OCD and depression. I have tons of anxiety even when taking both which is unfortunate but it's something I guess I have gotten used to. My untreated symptoms (without Klonopin) are severely bad. I have had HPPD for 11 years now but it didn't become unmanageable until 2008 after a bad night with too much drugs and getting a concusion.
My symptoms include severe static vision, severe DP/DR, tinnititus, electrical zig zags through patterns such as blinds or flooring, paranoia, anxiety, ghosting, things seem bigger or smaller than they really are, halos, etc. Also when I hear things that are at a distance they sound foreign and strange. An example would be some kids playing outside and they almost sound robotic. I could go on and on and I'm not sure if all are related to HPPD but I make one hell of a mess without Klono. Oh, lucky you for being able to drink coffee!
Dukkha - Considering how bad my HPPD is, I am already on a fairly low dose. I have never exceeded 2mg in a day unless it was absolutely neccessary. I have been a bit slugish lately as I have a lot of stress in my life and I have been staying in a lot. Regardless of that though I have been tired for as long as I can remember regardless of what I try. The reason I posted this was because I was hoping to receive some specifics as what to eat or what vitamins to take. Having HPPD makes me freakishly afraid to take ANYTHING (including vitamins) because I have no idea what kind of effect they will have on me. I took 5HTP once and it sent me for a loop! So I figured I better come to the people who would know from personal experiences. I guess I'm just afraid to aggrivate it in any way because of how severe my personal case is. If you could elaborte on any specific vitamins that would be wonderful.
Again, thank you both for your replies, it is greatly appreciated!
Happy 2012!
