I was a HEAVY otc user at 14 and abused them into my adult life. I'm pushing 30 now and dude, I've been there. I remember my first of many robotrips (you know the one that's just supposed to be a one time thing) and all of the crazy, fun, terrible, and completely overwhelming times that followed. I remember doing all of the research (erowid is the shit) and thinking I knew what i was doing. I didn't. I thought it would be a fun thing to try. I thought because it was they were otc they should be pretty safe as long as I was smart about it. I thought I could keep it from my family. I was wrong. Aside from my family finding out and losing all the trust I had built, there were a slew of detrimental side effects. To this day i cant stomach most otc pills or any cough syrup- I will literally vomit if I have to take them when I actually need them, so I usually just deal with being sick. Memory, speech, coordination, and sex drive issues are common- the more DXM you do the worse they'll be. Whatever you do, DO NOT SMOKE WEED while on them- I had 3 seizures ( that's how many times it took me to learn my lesson)- seriously I took 2 hits off a blunt stood up to pass it and fell over and started fishing out in front of my friends (I have never had an issue with seizures outside of smoking while on DXM this happened on 3 separate occasions and I've heard of it being an issue for others too. Some people may say they've combined the two without issue- they're lucky. Please do not risk it) furthermore because I was using them to self medicate as a coping mechanism for unresolved issues otc's were just the first drug I used, the others had consequences and side effects of their own and here we are now (Welcome to bluelight! ) so listen dude, I'm not going to tell you not to do drugs cause they're bad mmmkay. But I do want you to know that these things can have detrimental effects on you for the rest of your life, no matter how careful you think you're being, and they only get worse if you're reckless or careless. I have to live with the unforeseen consequences of my childhood actions but I hope at least you'll be able to avoid some of these pitfalls.
