If you are planning to quit alcohol after many years, it is a very positive step, especially since you have diabetes. Anxit 0.25 is mainly used for anxiety or sleep problems, and Erolol is used for blood pressure or heart rate control; these are not specific medicines to help stop alcohol. In some cases, doctors may prescribe medicines specifically for alcohol dependence, such as Naltrexone or Acamprosate, depending on your condition. Since you are diabetic and may be on other medicines, it is very important not to start or combine any new medication without medical advice, as there can be interactions. The safest approach is to consult your doctor, who can guide you on a proper plan, which may include medicines, gradual reduction, counselling, and support to help you quit safely and avoid withdrawal symptoms.
