I have a lot of stress in my life right now taking care of both parents that have major health issues..neither are driving at the moment and I doubt my mom will be again. Dad has dementia and mom has high BP, congestive heart failure and is diabetic (she won t eat correctly) and severely anemic at this point. Anyway, I am an only child and it is up to me to help with all shopping, dr visits, as well as watching medications for both to make sure they are taken, and taken correctly. I have had .5 mg alprazolam, but have been taking 1 in the morning and two in the evening. My PCP put me on 20mg Citalopram daily....what is the difference between the two and can I take the Alprazolam if needed. I have also been having a lot of back pain...am doing PT. I do take 2000mg Tylenol and 200 advil at night as well as 50mg tramadol for pain
