Sorry for resurrecting a dead thread, but I wanted to bring something up for the few other people on here struggling with this.
First of all... I'm not sure if I have SCT or not. I was smoking weed pretty heavily when I started this thread, which kinda makes me an idiot since marijuana is obviously going to induce some SCT-like symptoms.
Even so - and this is the main thing I want to bring up - I started taking DMAE while I was still smoking to combat the supposed SCT. It has its unpleasant side effects, but the benefits far outweigh them, to the point that I'm still taking it and don't plan to stop any time soon. I had significant benefits even while I was still smoking weed.
I stopped smoking about a month ago when I moved back to Indiana, and felt in some ways like my SCT/ADHD:PI converted into something closer to the traditional form of ADHD.
I forgot to take my DMAE one day, and couldn't figure out why my short-term and working memory seemed to die on me. I drove to Barnes and Noble that day just to chill and bum their free wifi, but I ended up taking a lot of detours since I kept forgetting where I was going. When I got there, I got out of the car and was actually looking at the building and couldn't remember why I'd come there, or if that was where I even intended to be.
I eventually realized I forgot to take my daily DMAE. I took an extra large dose the next morning and felt incredibly sharp all day. It really seems to help a lot with all of the symptoms I've associated with SCT. The only reason I don't see it as some kind of amazing cure is that I still have some trouble feeling motivated, though not as much as before I started taking it.
I highly recommend trying DMAE if you're still struggling with SCT. If you're curious, it works by converting to acetylcholine in your body. The side effects can include some sore, stiff muscles, especially in the neck and shoulders. It also raises blood pressure and makes your heart beat harder, but unlike traditional norepinephrine and dopamine-based medications typically used for ADD, it should, in theory at least, slow your heart rate down. The most annoying side effect for me has been cramps in my fingers. Sometimes they get locked and I have to stretch and massage them a bit to regain control over them. Honestly, I see it as a small price to pay in light of the benefits.
