So I was at the Phish show 2 weeks ago and I whipped up a batch of killer brownies. I ate 1/2 while my friends ate an entire one. I don't really smoke much anymore so I was seriously tripping out. My mind was racing 1,000 miles an hour and I was kinda bugging trying to keep my mind from going into a dark place. After a few hours I started coming down and getting a grip on myself but still didn't feel 100%. The next day I was feeling kinda sluggish as can be expected. My stomach was all messed up (I assume from the heavy drinking the past 2 nights) and my vision was kinda off like I was still stoned. I figured it would go away in a day or so and I didn't think anything of it. Well 1 week passed and my stomach and eyes/head were getting worse. Another week passed and while my stomach is getting under control my eyes/head is another story. It is kind of hard to explain exactly what I am experiencing but my eyes kinda hurt as does down my temples to my ears and my vision is blurry in a way but its also still clear to the point where I can read and see etc... I am sensitive to bright light and I see after images like if someone flashed in your face. I see the after image of objects for a sec or so when I look away. I went to my regular doctor and he isn't sure what is going on and suggested I go to the eye doctor which I am going to on Thursday. In any event, being a smoker/eater for about 10 years now I am not one to question this but I was curious as to if this could have ANYTHING to do with that brownie or if it is all just a big coincidence occurring at the same time. As I said, 3 of my friends ate twice the dose and they are all fine so my guess would be no but I am just trying to figure out what could possibly be my issue as it is really starting to freak me out and I just want an answer.
