I think that's the thing with withdrawal, I experienced similar thing but it's never anything major. I am planning on minimizing my intake, at the moment because I have no access to it, I simply just don't drink it 😄 thankfully, starbucks isn't something that's available everywhere here. I think it's a good way to detox too, going to a place where it's not accessible for a few months. It's not practical but works for me hehe
