You might be right about DXM's application to your own life. But I have vivid dreams all the time too. I speak not when the need to grind my teeth or when the need grips me to spew communication that feels profound at the time but is actually nonsense, but when I have something to say, and it generally comes out just fun. Any drug, any time and I start failing to remember the right word over and over again, I run out of things to say much less a fluent manner of saying them ...
I find it hard to believe that DXM could help your vision. Vision has been known to improve naturally owing to good nutrition, but I doubt that DXM could have the same reparative effect on the body as nutrients that weren't synthesized in a laboratory a few decades ago that just happened to help some people, some of the time with their coughing symptoms.
Taking DXM in such small doses each day strikes me as akin to someone taking an aspirin or a Tylenol each day. Recent clinical research has shown that a hefty portion of those taking aspirin each day to prevent or ameliorate heart disease die sooner than those with similar baseline conditions who don't take it every day.
Even something with years of study to support its daily use in humans (aspirin) is now being revealed to harm a great number of the people it was believed to help. Becoming an experiment of one for the effects of daily DXM use on the body and by extension the mind does not strike me as prudent, but it is your life, and your choice. I do not want people to be pacified into a complacent attitude toward DXM, however, that could lead to the same type of misery that DXM brought to me.
How long have you been dosing daily on DXM at this level? I've just looked up piracetam and all the effects you're describing sound like the piracetam could plausibly be producing them on its own. So what reason do you have to believe that the DXM is making any difference at all? If nothing else it is an increase to the daily load on your body for which cumulative effects are unknown and unresearched.
In addition to potential chronic effects, I remember that multiple times early on in my explorations of DXM, before I started dosing on 600 or 900mg and kept to 150 or 300, my heart would often start pounding in such a way that it reminded me of the gasping noises of someone struggling to breathe. Probably 300 times a minute or faster, which I simply started ignoring because the DXM quickly took my mind off it rather than measuring how long it lasted. This has recurred with acid and even with just pot, and I suspect that it is not a harmless symptom of an anxiety attack; I suspect that the heart-pounding starts, and then anxiety sets in because, oh shit, I feel like I'm going to die!
I've rambled a little bit so I'll cut to making my point. There is no research into the effects of daily DXM use at any dose for periods of months or years. A few weeks are as long as the studies I've unearthed have lasted. Many people report a subjective feeling comparable to brain damage in the wake of or even during a trip. Accounts of hospitalizations from DXM alone or in conjunction with other drugs proliferate on such sites as Erowid. And it's f'cking cough medicine that doesn't even do much to alleviate
coughing! Sobriety is more fun for me than being dazed and seeing shit and feeling like my heart's about to stop. And the nootropic you're taking is probably responsible for sharpened vision etc., not the DXM.
PS: I'm a druggie hypocrite. I'm on Ritalin so I'm writing so much.
