First three weeks were strange for me. Suddenly I craved sweets and I never ate them before because I wanted to be thin. I couldn't sleep much either.
That being said, I wanted off the roller coaster ride of wine, so I ate cookies, I stayed up til the wee hours reading on this site, I discovered how much I loved waking up with no hangover or headache, and I developed new pleasurable habits of watching psychological thriller type movies 😊
You run so that will kick those endorphins into high gear - do it! You will feel great in a few weeks. In the evenings, try changing up your routine. Play a game online - watch movies - drink carbonated water or tea to keep your hands busy, etc
