Good to hear Mets, I think that some anxiety about what we have done to ourselves is normal. Given you level of fitness and age, I wouldn't worry too much. The body is quite resilient.
I'm stressed to the max here due to an overload of work and that feeling of not doing anything well. I'm about a month into abstinence and grateful for that otherwise I'd be completely overwhelmed, as opposed to partially.
I'm quite ready for the long weekend too. Let's hope it's relaxing and stree free for both of us.
