Hi My Wife Has Been Taking Zoplicone For Over 12

Hi My wife has been taking Zoplicone for over 12 months alongside Phenelzine. The Phenelzine has been withdrawn about 3 weeks ago and she is suffering with a foul taste in her mouth which then travels to her stomach and causes pains on both sides of her abdomen.She then has severe headaches and hot sweats.The pains in her abdomen is not painful to touch externally but fells like raw nerve to her.Could this be a side effect of the Zoplicone
