Hi. I have been taking 5000mcg sublinguals for a week following advice and research. I thought I'd go for the biggest dose I could find. How long do they take to have any effect? The reviews on Amazon were fantastic, but I've noticed nothing at all.
I've had my six loading doses, I've not got anti-intrinsic factor antibodies and I've been waiting for weeks for a follow up appt with my GP, hence the supplementing (I'm taking folate too). I should have had more doses as I have tingly toes and a twitching eye, but he was very reluctant and has not yet arranged for any further injections.
How long should I wait for the sublinguals to have an effect? Could I increase the dose? Or should I think about self-injecting?
