Replacing addictions

When I was using, i just replaced drugs with other drugs. Now i quit all drugs (except for caffeine)

I'm 3 weeks sober tommorow, and i'm so glad about that. But i spend a LOT of time on social media, porn is starting become a problem, i drink way more coffee and energy drinks

I know all of these i 100 times better than drugs. But I don't want to get addicted to these things instead. But it's kinda also what 'helps' me to not drink, since it's better than nothing. I kinda wanna to quit it all, but i'm afraid it's gonna suck a lot more and potentially backfire, because it gets too much (or to little)

From what i understand it isn't that uncommon. Replacing drugs with other addictions

Do you guys have some advice on how to handle it? Should I just let it happen, and work with when i've been sober for longer or now
