Drinking beer

Oh you can! Accompanied with some hot and spicy chicken broth. Google says, chicken soup cure the cold and I agree. But, if you take medicine, generally cold tablets contains drugs that make you sleepy and even a little drunk can get you high enough to misjudge during working with machines and driving. Many tablets of cold also contain paracetamol which damage liver in excess. That with alcohol is bad for you.
So, consider beer to get rid off from your cold.
