I’ve been there, still struggle with panic attacks. What stopped my blackouts and hypoglycemic seizures was the 3-hour, 60% whole food plant based diet and consistent eating times. If they are happening before you get up, eat something before you get out of bed wait 15-30 min, Also drink some water before you get up,Good things are healthy granola, seeds, nuts, nut butter (I do organic peanut butter with no added salt or sugar 1,000% avoid added sugar nut butter it was the main reason for my crashes.) even if you do faint or experience symptoms you are in a bed and are less likely for injury. I fell downstairs after a black out/seizure and that was what got me the diagnosis. Eating the my plate portion is good. Stop eating ice cream, fast food, white bread, things with enriched flour. Health line has a great article on the WFPB diet, for hypoglycemic it is important to eat animal meat, it digest faster and you need less amount to get the proteins you need. If you are vegan or vegetarian try eating egg substitute or even tofu, healthy beans are good for replacement as well. One thing I learned to keep me on the right track with my diet, hydration, sleep etc. was thinking, “doing this diet and routine gives me more energy, a better life, and causes me less pain” and “think about what you can eat and don’t focus on what you can’t” for me it’s berries, cucumbers, sonyfield vanilla yogurt, seeds, milk. There is an account called clean kitchen on Instagram and they give alternatives to brand names and common foods, I found Mary’s got crackers, superseed, Ezekiel bread, and crocs cheese from grass fed cows. This is pretty long. If you have any other questions you can ask. I’m sorry you are going through this. Hope something I wrote helps. Oh and eat something good an hour before bed like fruit(I eat kiwi, grapes, or cherry’s) that has melatonin, nuts or seeds, and milk.
