I just started having what seems like digestion problem . Ive taken Prilosec for around ten years for acid reflux. still taking it as well. I was a heavy drinker for around 20 years. I recently quit drinking about 3 months ago. I now have severe anxiety attacks and all the typical symptoms with that. I seem to be afraid of going anywhere and driving as well like paranoid. I now have had in the past week or two feeling light headed , dizzy and bloated after eating anything. It feels like I will passout as well. please help
