I have been taking 100mcg levo since May and have now increased to 125mcg but for no apparent reason some days I have been getting a severe tense feeling and then have a panic attack. I cannot blame it on the increase of levo as it started a few days before the increase. It comes on around midday and also around 9.00pm whilst watching T.V. Sometimes it can last for an hour or more. Does anyone have any ideas what could be causing it.
Any advice greatly appreciated.
Many thanks browny
