Hashimoto's and dizziness/faintness?

Hi all,

I've recently been diagnosed with Hashimoto's, and started on 25mcg levo about a week ago which I take first thing in the morning. For the last few months I've been experiencing faintness most days around mid morning and often later in the day that can last several hours, sometimes manageable sometimes really bad although I haven't actually passed out. My diet hasn't changed at all, I eat a substantial breakfast and always make sure to eat something when I start feeling faint but it doesn't seem to make a difference and I'll still have waves of faintness for hours afterwards. I drink plenty of water throughout the day too. It's a different feeling to the tiredness and fatigue which I also get. I had relatively low B12, Vit D and ferritin when tested around a month ago (still within normal ranges). I wondered if these could be causing it, but have been taking supplements for around a month now and haven't noticed a difference.

I haven't found any mentions of a connection online other than a few in forums, and while dizziness is mentioned on the Thyroid UK symptom list it doesn't specifically say faintness. It's really horrible and I'm scared it's going to cause me to injure myself by falling over, which I've come close to a few times. Has anyone else experienced this? Is levo likely to help when it eventually kicks in?

Thanks for any help.
