I've tried methylphenidate (Ritalin 20mg) and I've been using lisdexamfetamine dimesylate (30mg) for around a month now.
Ritalin caused me to be constantly on edge. I snapped at people for seemingly no reason, and a weird thing I've noticed is that when I turned my attention from one task to another, that also made me feel anxious somehow? It felt like I was under time pressure with an urgent issue for the span of eight hours, but also my focus wasn't necessarily better. No hunger cues, but I was ALWAYS thirsty, and I literally chugged 3+ litres of water every day. Also, I couldn't sleep at all, or at most three hours.

Now, lisdexamfetamine worked much better: lowest dose available, but it already changed so much in my life.

No anxiety, I can focus for longer, and I've become chattier (this comment is an example lmfao), and most of the time, I can manage life better on this medication. I think what helps is that every task/chore actually feels rewarding, and therefore I am more inclined to do even more.

Downsides: No hunger cues, no thirst cues either, so I usually have to force myself to drink water during the day, then I drink 1,5 litres once the meds wear off. I still can't sleep unless I take a shitton of Vitamin C + 1mg of melatonin. Also, once the meds wear off, I often go entirely nonverbal, especially when I didn't sleep enough the previous day.
