I am doing 800mcg methylfolate daily and 5mg. methycobalamin injections every 3 days. well I ran out of b-12 injections right when I moved, so I had to quickly find a doctor and find a compounding pharmacy to fill it, but I couldnt get all of this done in time, so it had been 8 days without b-12 and I crashed an unbelievable amount. I was taking 2 naps a day and going to bed at 8 pm. every night and couldnt stay awake, I have been fatigued but this was beyond anything I have ever experienced, it was almost like my body had to pay back all the extra energy I had been getting since doing the methylation protocol. I still havent gotten the b-12 injections script filled but I happen to have a baggie with 3 grams of pure methylcobalamin powder in it. I licked my finger and stuck it in the powder and then stuck my finger in my mouth and wow, I was back and have plenty of energy today. I do wonder if I am going to get the script filled or not now. I might just put this powder into an oral spray and squirt it into my mouth, I probably got 50mg by licking it, but it was plenty and did the trick.
