I have only done coke for 3 to 4 months so I really hope its not permanent damage cuz I know other people do drugs for years and are ok and I was only doing like 80 dollars a week alot less than other people. I smoked some weed two weeks ago and I tripped out like my nervous system went crazy I think.I think it was being high mixed with anxiety attack. And my vision wasnt normal for days and my body felt weird throughout. Well it was getting better and then I went and did some cocaine 1 week ago cuz I thought I wouldnt trip out because I have never had problems with coke. Well I did like 6 lines the whole night which is nuttin compared to what I usually do. Well anyways my heart felt like it was going to explode that night which had never happend before and my leg started hurting and both my legs went numb. Well that night I only got 30 minutes of sleep. And what had happend when I smoked the weed was worse now. My vision is all weird like when I look right everything moves right and when your staring at something you can just tell your vision aint ok. I can still focus to watch tv though. Well so my visions all messed up and my whole body feels weird stuff throughout like sometimes my hands feel weird or my feet or legs just anywhere throughout my body. Sometimes I think it is better like when I first wake up and I think it was better the first three days. I think I made it worse by drinking soda cuz of the caffiene which is my bad cuz I didnt come to the conclusion that I had bad anxiety until today so im gona stop drinking caffiene and I also think I made it worse by worrying myself out about it. I will never ever ever do drugs again. I wont even drink alcohol or smoke tobacco. I just want to be sober and live my life normally. So some replies would help me out here.
