I had 2.5mg of thc every day for ~7 years. I couldn't remember the last dream I had when I quit thc in August. After not sleeping for 2-3 weeks I started having vivid nightmares every night for about a week. I'm still having extremely vivid dreams since, but they're no longer all terrifying. Sleeping better than ever and my anxiety is also better than ever.
I run a 3d printing business, design, manufacturing, CAD/CAM, designed my own marketing materials, website, etc etc from my 8G M2 Macbook Air, never once did I feel like I needed more RAM.
Botany. Install iNaturalist and start researching and tagging stuff. It gets you outside more, gets you excited about places you’ve been 1000 times and gets you wondering what new thing you’ll see next. Start with anything that is flowering. Flowers are the best and easiest way to identify most plants. Seed pod and cones are the next easiest. You’ll be familiar with most of the things you’ve wondered about in a couple weeks or months and hungry for more.
