I’m feeling the exact same way, H. I just passed up a canoe outing with my husband and kids today because I really needed to rest. I’m not sure there’s a good time of year to do this though. I think it would be even harder to be starting out near the holidays.
I just got back from a 2 week vacation in France, where I got to watch everyone eat the most amazing food. I have to say, traveling without eating out does diminish the experience, but I appreciated feeling so energetic and normal on the trip, so I persevered. I wouldn’t be surprised if you feel much better on vacation than you do now. It seems like there’s a bit of energetic magic that goes on with vacations — people often feel better without doing anything different, it seems.
Wishing you fast progress and a great trip,
