Great job on day 6! Yeah, the addictive voice will start trying to meddle with you at times - but don't listen to it. If you can avoid it, I'd stay away from Dr. Google and what folks have to say about supplements - leave that for a conversation with your doctor. There's some good info on supplements out there on the internet but also some horrifically bad stuff.
How about going to a meeting? Or a movie? You could take a walk, plant a box garden, cook a homemade pizza, go fishing, a lot of different things.
It's also important to realize that while withdrawals are no fun, they are temporary - and they will end. You are in the thick of them right now but they WILL get better. And unfortunately there is no magic pill or supplement that will just make it all "go away". And using now would make it doubly worse...as you'd have to start all over again.
