Does being in ketosis make you feel a bit odd?

Hi there
I am on day 3 TS and today have felt out of sorts. I have had a headache which is easing but have felt soooooo tired and also dizzy for about 1/2 hour earlier and a bit hyperactive !?!
I know everyone will have different experiences, wondering if anyone else has felt like this?
Feeling ok now, although still tired and a bit cold
And, how long does it last for or is this how I shoud expect to feel?
Many thanks x

This sounds pretty normal to me - I prescribe a warm bath and an early night, you should feel a lot better tomorrow. Try adding some water or if you like it hot green tea. I use that for most 'odd' symptoms and find it soon passes.

Thank you
Was a bit worried feeling so yukky!
I don't really have anyone to talk to about my weight / loss - it's always been a bit of a running joke about me being on another diet so I am keeping this to myself....your advice is appreciated, I fell asleep on the sofa!
Thanks x
