Some combination of drugs that I take in the morning cause me to be extremely tired. I take a multi vitamin, vitamin B-12, Vitamin c, calcium, fish oil, vitamin D, 1 aspirin 325 (MD order because I had a DPT when I was 21), oxybutynin 5mg, meclizine 25mg, tizanidine 4mg, fluticasone 50mcg spray, pantoprazole 40mg, clonazepam .5mg. I have bad digestive health, vertigo, and need antidepressants for panic attacks. The only recent change was the oxybutynin as Humana didn t cover a different bladder control medicine.
