When I don't lift for a few days my muscles get "itchy" and antsy until I lift again. It's a really uncomfortable feeling to stop if you lift weights regularly.
Crack addicts also get withdrawal symptoms, it's not necessarily a sign of being in a good situation. I'm glad for you that you're in a position where your urges steer you in a healthy direction, but that doesn't make "listen to your body" always good advice.
i lift 3 times a week (strong lift regimen) - i never had lifting craving in last 3 years. so.... bodies are different :)
Try laying off leg lifts for a week while working an office job, even through weekends. This means spending most of your time sitting or sleeping.
