I do these things too! I've had pretty bad tech neck (great name for it too, btw) for a couple years, all because my first job had me working on a laptop for just a few months. Crazy what impact months can have on years.

But one other thing I HIGHLY recommend is getting a standing desk. That's brought my body much relief. I have a chair that I can switch to if my feet get sore, but I'll switch back to standing after not too long.
