    • Hi all, ill keep this short as I tend to praddle on... I am having a hard time distinguishing what day of the week it is, what time of day, and my cognition is almost non existent. I also suddenly have poor coordination and my arms and hands feel at times like lead. I don’t understand the world completely. in order to continue trying different treatments I have to work so I can stay with my folks. I am currently employed but am worried I won’t be able to maintain my job. I have to be able to have a basic mental map-a sense of sequencing. Yet I’ve, as of now, lost that ability. It’s like I am not “locked in” to my day. I know these things take time just any advice would be very much appreciated if you’ve ever dealt with such symptoms. thanks a million
    • Hello people . I’m new to this website and idk how active it is here but I just wanted to tell my story as short as possible. I first started taking LSD at age 16. At age 18 I had my last LSD trip. Not knowing it was going to be my last. That last trip was different. It wasn’t bad or it wasn’t good . It was different. But that same day I had smoked once it started to go away. And I was driving and all of a sudden I lost connection to reality . It was scary. And I didn’t know what it was . A week later I had this flashback. And it tripped me out. That night I woke up at 3 am in the morning to thunder and rain . When I woke up I felt scared. I thought I was feeling that way cause of the thunder. I’m a painter and I have this painting of a fish I did on my wall. I remember looking at it and it looked different . I got out of bed and I went to the bathroom and I saw myself in the mirror and I just felt very very off . And I knew something wasn’t right . I was fucking terrified. I went to my parents room and took a shower in a bathroom they had in they’re room. I remember showering and all the thoughts going thru my head . I felt as if I wasn’t in reality same time I knew this had to do something with my constant taking of LSD. I got out and I slept in my parents room on the floor. I was a 18 year old. Sleeping in my parents room cause I was tripping bad . I had to . My little brother was already sleeping on the floor so I slept near him literally grabbing on to his foot while sleeping cause I needed to feel like I had someone normal connected to me so I can stay sane. I didn’t say anything about what I was feeling. Idk how but I fell asleep . I woke up the next morning and that was day one of HPPD. Everything was different . Everything. My life flipped...... that was a year ago. October 28, 2016. And till this day I still have it . It has its ups and downs . And my answer to it is to stay bright, stay sharp, love yourself and love others. Keep yourself busy and please stay sober. Spread the word.
