Hi , I am new to this thread. My question is , I read about fredd methylation protocol here on this forum and thought to give it a try. I ordered Jarrow b12 5000 mcg. After 6-7 hours of taking first sublingual tablet under tongue i got tremendous amount of energy , and this continued for 2-3 days. After that everything was back to normal , no more extra energy. And now b12 sublingual tends to make sleepy throughout the day. But I continued to take sublinguals , i noticed when i am on b12 i no longer get constipated in winters like i used to be , and as soon as i leave b12 i get badly constipated , i took betaine hcl to rule out possibility of low stomach acid so low stomach acid is not the culprit here. I know people have better understanding of methylation on this forum , can anybody help me out on understanding what is going in my body , specially how is winter constipation totally cured by methylb12 ?
