Hello, I'm six days into an increase from 12.5mcgs to 25mcgs. I am feeling quiet strange on and off - heart palpitations, a bit wired, a bit sick, feeling like I could panic but know I won't, and very tired. I'm sure it's my body adjusting but I would love some reassurance. I'm subclinical and had to beg my GP to go up to 25mcgs (he kept telling me I'm depressed) so I don't think he'll up it again!
