Hi There- I Have Been Taking Ranitidine 150 Mg Twice

Hi there- I have been taking Ranitidine 150 mg twice daily. I am thinking of discontinuing this medication because I have been experiencing some heartburn after taking it. I eat a good diet, mostly veggies, fruit and chicken. I drink a couple of glasses of wine per day and know that it too much alcohol. I am 72 years old. I exercise regularly. I have diabetes and I weigh 140 lbs. My iron count is 22 and I have my blood work done every three months. I also take Lipitor and Ezitrol as well as Metformin. Any advice for me. Thank you!
