Marijuana withdrawal?

One of my friends is a pretty heavy stoner. I think what you described, but minus the decreased appetite, it didnt effect her like tht, plus the digestive **** (though its hard to tell with her). Cause its a mental and not physical addiction, the symptoms tend to be more psychological- she gets kinda jittery and not so bubbly, and finds it more difficult getting to sleep, as she isnt as calm. Thats about it i think.
