Hi there and Welcome to HealingWell!
I am assuming since you use the term "GP" that you are in the UK? (As am I!) It sounds like a strong candidate for a seizure but there are other things it could be and you would be best placed to see your GP first. When you say you are waiting for a neuro, do you mean on the NHS? If so, then (depending on where you live) it can take up to 6 months. Do you have any other conditions that may just have gotten worse?
Im sorry I misread your post. I must have read neuro as habit rather than naturopath... must have been tired that morning! lol. I still think it might be worth seeing your GP as well. The episodes sound like seizures to me and its definately something that needs to be checked out.
