Hi. I get weak, shaky and feel like I'm going to pass out. Had bloodwork show low B12, iron, folate and blood glucose. Took supplements and got all back to normal. Been eating 3 meals, 3 snacks and more a day. No processed foods, balanced meals. Been testing blood glucose, low or high levels don't seem to correlate with the weak episodes. I have to lay down and wait for it to pass, scared I will pass out. Any ideas?
