Hi. I've been on thyroxine for years. A few weeks ago I went for a (very overdue) blood test and the results showed my thyroxine levels were way too high. I thought they would be because I'd been having hyper symptoms - anxiety, not sleeping etc. Anyway they told me to drop it to 175mcg for a couple of weeks but then I asked if I could take it down to 150mcg as I'd felt so rubbish and my levels were so high. Doc said fine and so i did. Ten days after my latest change I started to feel a bit dizzy and lightheaded. This has been going on for the past week or so. I'm presuming it's my body reacting to the dose change but wondered if anyone else had experienced this. It's making me feel really anxious. Thanks.
