Went to the GI Dr. they said to take Pepsic AC max 20mg, twice a day for 2 weeks. I took it for 4.5 days and was mentally destroyed. Anxiety, depression, and an off feeling in my gut. I quit taking it and a couple days later got this horrible bitter taste in my mouth that I still have 7 days later. I'm hoping it will go away. Has anyone else experienced this on this drug? Thankfully mentally I'm feeling better, never again will I take this drug or any PPI!
