Hi all. I've been very well, and had settled to a fortnightly SI. I've worked myself up to leading a reasonably active life, but decided to take things to the next level and have upped my exercise, although not significantly. I just need to get fitter. The upshot has been that I've had to up my SI to weekly. Has anyone found that once their body gets used to the new 'routine' that the need for the B12 has reduced again?
A couple of years ago, I experienced a few months when my body seemed to need less, but then things escalated and I was back to fortnightly. It just seems so wierd.
