Since starting my three loading doses in September my biggest problem has been insomnia and it has been a real struggle. I'm now waiting for the three monthly maintenance dose at the end of January and in sheer desperation I started taking oral B 12 supplements ten days ago. To my astonishment my sleep improved straight away and up until last night things have been so much better. Last night however I seemed to be back to square one, waking up every hour and not sleeping at all from 4.00 am. I have been taking 1000 ug in the morning and again at bedtime and because I tested positive for intrinsic factor antibodies I don't know what I expected so was very happy to be sleeping better. I have read that some of the oral B 12 still gets used so maybe that's what was happening.
As I still have a month to go before the next injection, would a higher oral dose be a good idea? I understand overdosing is not possible. Very grateful for the information and help given by members here up to now. I've learned a lot but still have a long way to go !!!!
