Hi everyone, this is my first time posting on this forum. I'm 19 years old and I was a vegetarian for 8 years. Last summer, I tried to switch to veganism and started to experience symptoms of B12 deficiency. I have been taking mb12 for a month and it didn't seem very effective until I greatly increased the number of potassium rich foods I was eating––raisins, carrot juice, apple, avocados, etc. After doing this for two days though, something seemed strange––I felt very wired and I couldn't sleep. When I did try to fall asleep, I'd feel a pins and needles sensation all over my body. Soon enough, I completely lost my appetite and I started experiencing arrhythmia and tachycardia. Within two days, I started experiencing panic attacks. The panic attacks got worse and worse and I eventually ended up in the ER. The doctors there assumed that the cause of my panic attacks were genetic, as he did a basic serum test and couldn't find anything. He said my EKG was slightly off though. I went to another doctor and he also assumed that it was genetic. I have a much closer relationship with this doctor though, so he will be willing to work with me more. I'm wondering if I have an induced magnesium deficiency? Or maybe something else?
