2013 i took concerta 54mg not prescribed , and drinking redbull and alcohol. next day woke up, could not breathe , thought hear attack. several docs, gerd diagnosis.. can this cause gerd? nerve problem? no gerd prior to that night. on ppi daily since?

It is known that coingestion of alcohol and concerta increases the plasma level of that stimulant medication in your body. I believe that GERD wasn't the cause of that scary reaction but was caused by excessive amount of stimulant in your system mimicking a panic type reaction. I'm surprised that you didn't land in the hospital emergency room.

The combination of the Red Bull, alcohol and concerta Moreno than GERD are more likely related to this episode. Watch for signs of shortness of breath, difficulty exercising and cough. Avoid excessive alcohol and caffeine intake. Do not take drugs that are not prescribed by a physician.

Fully agree with my colleagues, as do believe your 2013 episode was a consequence of Concerta, alcohol, and Redbull combined toxicity. You were lucky then, and trust you will ask your doctors' advice regarding further OTC self administration in future. Gather the GERD is ongoing issue, and under control.
