B12 injections and insomnia

[Hebe2020]

Good morning all 😊. Can I please ask about people’s experience of going through the initial loading doses. I’m on my fourth, which I had about 8.30 in the evening because the GP has allowed me to SI and I was waiting for my daughter who’s a vet to do it for me after work. Last night I had a dreadful nights sleep. Very tired and went to sleep before 11 but woke at 2 something and was buzzing. I have tinnitus, which I haven’t had for a while, and feel quite shaky and with palpitations, which may just be tiredness. Is this common? Is it better if I have the remaining two injections in the morning? As tinnitus is a neuro symptom should I ask my GP for more injections after the first six or am I already overloading my system? Thank you for your help. There are some very knowledgeable people here.

I noticed in my first set of loading doses that I was full of energy at first, luckily I was having mine in the middle of the day! I didn’t notice that as much on my second set of loading doses.
