Not saying these would work for you, but they do for me.

Go buy some really GOOD tea, learn how to make it right. Make yourself some tea, sit outside somewhere serene, back yard, anything would do and just try to appreciate what you've got and the time you have being alive.

Get a pet and really pour your love into it, if it's a dog, walk it, feed it, play with it, teach it.

Drum rudiments. This is an every day one for me. I just sit there with a practice pad and do simple rudiments in time and get lost in the rhythm of it.

Get lost in a book.

Go for a long walk/hike in a natural environment.

You said no alcohol, so I guess you could modify this one but meeting with friends and having a pint and some laughs is very relaxing to me.
