Sleep issues is tough, it took me 5 years and a friend who is a doctor. The Dutch medical system failed me but my doctor friend saved me from a lifetime of insomnia. In my case it is: 0.3 mg melatonin + 7.5 mg mirtazapine (anti-histamine, it makes me drowsy) + meditation + sleep hygiene. Your experience may be different.
Math academy: I need to be told what to do. Designing my own curriculum is too much. Also, I need to pair it with a solid LLM because I have a lot of why questions and of course channels like 3B1B.
iPad: I tried pen and paper multiple times. The thing is: sometimes I just want to be in a slob and lie on my bed in weird ways and still do math. I found I need a pen, I can’t do it on pure memory. An iPad where I can do split screen: Math academy + MyScript (formerly Nebo) is nice. An Apple Pencil Pro is really nice because I don’t need to worry about connection issues.
I was doubting between: ipad vs pen and paper (the nth retry) vs Remarkable. I am happy I got a second hand ipad air. I can stick to this routine.
Low-key life changing.
I know this setup isn’t for everyone.
though I'm conflicted about the whole "use bed only for sleeping" bit, I find I can't really sit down or be too far from my bed or else I lose the tiredness by the time I jump in bed. Being AT bed works well, I just turn to the side and close my eyes when I feel tired.
If it’s emotional, I recommend doing a meditation retreat at dhamma.org on the off chance it helps. It helps for me, somewhat. It’s a donation-based retreat and quite serious too (10 days).
