I had a buddy go through it, and he said the shakes, sweating, and anxiety were just the start. It’s way harder than people think, and for some, it can even be dangerous if they try to go cold turkey alone. He ended up going to
rehab where they knew what to look out for and helped him get through those first rough days without things getting out of control. It made a huge difference having people around who actually understood what he was dealing with instead of trying to tough it out solo.
