Will it kill me, reduce, or lessen/strengthen the effects of acid (the drug) if im on celexa and seroquel (quetiapine)?

Problematic. Wow! since you are expressing concern about the effect of the acid and not the seroquel (quetiapine) or Celexa that speaks volumes about your priorities. The use of acid may render your psychiatric treatment ineffective. This is a reciped for disaster. Please get help from an addiction specialist & inform your prescribing physician about acid us.
