Whenever I try to learn something new it feels like I've only barely understood it. I can never get that feeling of something clicking in my head. I'm not sure what it's called, but it's like in school when you're trying to understand a certain concept and then it finally clicks for you and you get it; it's like a feeling of deep understanding.
When I first took Wellbutrin a few years ago I took it with piracetam and choline and when I read wikipedia articles I was able to grasp the information very easily. It just made sense when I read it. Everything clicked together and it felt like I understood it deeply.
I can never get that feeling now. Everything I read, no matter how simple, feels like it's difficult to understand. Nothing ever clicks and makes sense. I've even tried Wellbutrin several times again, but without piracetam and choline, and I didn't get the beneficial effects on learning. Actually, it seems to worsen my learning now. It also seems to worsen my short-term memory whereas before Wellbutrin had a very pronounced benefit on both short-term and long-term memory. Maybe it's because of the piracetam or choline or the combination of both? Wellbutrin is an antagonist of the nicotinic acetylcholine receptor and this receptor upregulates quickly so maybe the choline was working synergistically with Wellbutrin to enhance memory and learning?
Regardless, I've tried various other substances like Selegiline, Modafinil, Rasagiline, Modafinil + Rasagiline, Moclobemide, Moclobemide + Selegiline, Rhodiola, Maca, Ginseng, and others that I can't remember now, but none of these have had a positive impact on my learning ability. I still feel slow when learning new things.
What affects the clicking or understanding part of learning? That feeling of deep understanding?
