Sounds to me more like your side effects are coming back that the cannabis use to take care of.
I don't believe in cannabis withdrawal symptoms though there are a sort of withdrawal from anything that you like to do. I love having one cup of coffee in the morning. If for some reason I don't get one I tend to be mopey and slower to get going. If you like having cheese burgers and then you can't have any any more it makes you sad. All things are habit forming if they make you feel good. Its always a question of moderation.
