Most likely, it is: Because you have developed physical dependency on one or more of these drugs - most likely the alcohol. At low levels of dependency, insomnia and mild anxiety are the major symptoms. There is also a discontinuation syndrome from marijuana marked by similar sleep problems and irritability. If you are a week into it already, you are most likely through the worst of it.See your doctor if continues.
