I have always been extremely sensitive to medicine and if there's a side effect, I'll surely have it. I questioned my doc at length about possible side effects of Omeprazole and was told they are very minor, very uncommon and include nausea, diarrhea, and dizziness. Within an hour of the first dose, I became flushed, itchy, and felt heaviness in my chest. I have suffered from vertigo in the past and had a spell yesterday. I suspected the drug because I take nothing else currently. Yesterday I took the second dose and all day had an uncomfortable feeling of anxiety, itchiness, heaviness in chest, had difficulty sleeping, felt heart palpitations, and sporadic hot flashes, sweating. I am afraid to take the third dose; particularly after reading how long it can take for this stuff to clear your system. I'm a fan of holistic medicine and natural therapies and will call my doctor first thing Monday to discuss alternatives to chemistry-altering, manufactured drugs!
