I was initially given Ritalin (10mg pills) to try out; I cut them into four pieces each and spread it over the next month and a half. It worked well, allowed me to work, and felt 'smooth'.
I ran out, found that they are expensive here (I was diagnosed and prescribed a week of pills - 14 - initially in Taiwan), and went to Thailand (neighbouring country) to get more. Turns out the place I went to only had Rubifen, a generic variant. It was about the same as I paid for Ritalin so I thought why not, and got enough to get me through the next year.
Fast forward a month and a half... when I am on my 'off' days (Sat & Sun, when I don't need to work or study), I am now reacting to things pretty badly. I snapped at my partner very easily, I almost put a window through because I knocked a bottle over, and generally had a miserable weekend. With Rubifen, I feel fine, able to complete tasks, work and whatnot. Without it I'm not sure I should be around other people. Is this normal? Will it level off or should I go and get something else instead?
I don't know what Xcode is so yeah, I haven't been found wanting with my 8GB M2. Videos, downloading, web browsing, writing, chat applications, some photo editing, games (what I can actually play on a Mac, anyway), all good here.
16GB+ is obviously going to be necessary though, and not exactly that expensive to put into their base models so it should be put in soon.
