    • There is such thing as acid afterglow, give yourself a few more weeks and youll be okay. Stop payimg attention it tho. 
    • This was my first LSD experience Had 2 and a half gummy bears with drops on them, I assume 250mg each not sure. the trip wasn’t too intense.  I heavy started at the patterns on my walls as they melted for hrs, thats about it.  The next day I noticed the patterns in the wall would still melt if I looked at them long enough.  For about a week after the trip my right eye  was a little blurry and tired.  Felt a little fog in my head.  After a night of binge drinking I was all better the next day 100% my self no issues. Than the alcohol left my body. Around 9pm everything was wavy again worse than ever and I was having trouble reading as I couldn’t focus and the words were moving. The vision in my right eye was blurry. Its like ALL my vision was peripheral vision. Everything around what I’m focused on was wavy. The next day my right eye was a little bad until I took some Tylenol and it cleared up. I had two more days of being completely  fine. Than out of no where I felt the right side of my brain fog up and my vision got a little blurry and wavy again. When I focus on something it begins moving and melting in just the slightest way.   Its not super intense but its very VERY annoying it feels like my right eye is about 1mm off focus from my left eye and when things melt or wave its ever so slight.  I don’t have any signs of depression other than the anxiety from this happening.  Also my head sometimes doesn’t feel normal but doesn’t hurt. This comes and goes      Have any of you ever had anything similar ?  If so how did you cope? How long did it last?   I am now a 2 weeks out from my trip to this day.    The fact that I have had a few days with no effects gives me hope it will pass, but I’m not sure whats triggering it.  Today I’m trying to wear sunglasses and see if that helps.  I have also been staying away from alcohol and anything that would effect me in a negative way thank to advice on this forum. Id also like to say thank you to everyone that has posted on here. Finding thins site has really helped me a lot and I appreciate all of you ! 
    • Come on man, drink alcohol and slowly poison yourself like the rest of the population. Drugs are wack, they'll do nothing but slowly change you for who you are, anxiety will pop up here and there where it previously wasn't, your memory will slowly get worse, and 5/10 years down the line you'll be a different person begging to get back to your original self. Life can be amazing all by itself, you don't need drugs, it's taken me a year to get to my old self after a few uses, I appreciate life now, without drugs and alcohol. I know my vision may never be 100% like it was, but it's 50% better now and so greatful.

      Does it feel as if you were just looking at life through someone else's eyes ? Not truly feeling your surroundings . Almost as if you were present in body but not actually there? Fuckin sucks.
