Hey guys.... Can one of you well informed people answer this for me. I was chatting to my sister in law about my b12 injection, I was talking about spinning and how excersise seems to use more, trying to explain how it works and told her " it's like filling up you car with fuel and knowing it has to last 12 weeks" so the more running around you do the quicker the tank runs dry. So she responded with, if you top up every day with the sublinguals will it run out as quickly?????? As I have t2 diabetes I really need to exercise but find it runs my tank dry much quicker and by week 4-5 I'm exhausted again. So it seems to knock 2-3 weeks of my usual time before I start suplimenting again. But I have only been suplimenting once my symptoms start to come back. So should I be suplimenting continuously that is my question?
