I know it's different for everyone, but for me the worst of it took about three months to get manageable, then things just slowly got better. A year later I still have some problems that surface more when I get tired, but compared to how I was in the beginning this really is nothing. I suggest trying to rest as much as possible. I found that when I tried to push myself to get back into my regular routine (hard not to do when you're bored as hell at home) things got worse again quickly.
