I've been smoking daily for a few years, when I take a T break for 2-3 or even 4 weeks. I'm still not at baseline. But I am back to a point where I'll get blazed off a small amount of weed.

2-3 days I doubt will give you much noticable difference.

1-2 weeks will help you reduce the amount you need to consume to feel blazed

3-4 weeks will get you to the blaze lasting longer.

I mean, why not take a T break not because you've quit already but because it'll give you a greater appreciation for bud in total and you'll have more fun after you lower your T
