What is life like with meds?

I find it hard to conceptualize what life would be like when medicated. Afaik its “just” better but how exactly?

What are the specific things you can now do that were challenging before? How does it affect your relationships? How does it affect your work? How do you feel when waking up? And how do you feel when you fall asleep?

Additionally, I'm interested in learning about any side effects that may have come up
