I was and is in the same boat as you. the mb12 helps but seems to aggravate a lot of things. It makes me so emotional, i get really bad brainfog from the mb12 (when im off i dont have brainfog), i get irritable, depressed and other things. Basically my symptoms worsened. but then again, i'm sleeping better and my adrenals are doing better as in i can handle stress better, i dont have heart palpitations anymore, etc. so it's kind of a tradeoff. sometimes i think, wow, this was a good trade off, gotta keep going. and other time i think, wtf i'm worse than i was before. The biggest thing about start the mb12 for me was, whenever i eat especially carbs or sugar i get REALLY REALLY bad brain fog, depressed, anxious and feel derealized. if i get off the mb12, doesnt occur so i dont know what the deal is. and i had to cut down the ab12 because even more than 200mcg for the day i can't sleep.
