I'm doing meditation and breathing exercises which helps a ton for mental anxiety.

However every few days I develop a feeling of strong physical anxiety around the chest and/or stomach area. Usually accompanied by racing mind, urge to pee, dizzyness. This can last up to a full day before it dissipates but obviously messes with sleep if it starts in the evening. Sport, cold showers and mental exercises help but not enough. I'm fine dealing with this during the day, but it would mean the world to me if I could have a little help during the night.

Discussing this with my doctor I tried out Propranolol and Prazosin, but both did very little to alleviate the issues and came with uncomfortable side effects.

I was hoping Clonidine worked in a different way so it would be worth a try.
