I just started today as well! I'm super excited to get my health on track, 2018 was a very unhealthy year for me. I'm very into craft beer, and I did not balance the heavy beers with healthy foods and exercise - which led to eating out CONSTANTLY and 20 pounds put on and overall feeling sluggish and down on myself.
I did all my shopping and meal prep yesterday and it was a tad overwhelming - I'm going to need to get better at meal prepping. I wanted the first week to be delicious, so I went all out on my groccey store trip, but I think i went a tad overboard.
