All I could manage for the first while was to just sleep. My wife knew what was up and so left me to recover. I also spent a lot of time here on SR. I have my regular threads that I post to every morning and evening. You should drop by and say hello on the weekenders thread, a new one starts every Thursday, it's full of people with great advice.
My children are grown too, so I don't have the stress of a new family like you.
