of hyper feelings are from your Adrenal Glands producing more then needed Cortisol, thats a pretty common withdraw, youll probably feel those more in the morning.
Twitching, Palps, shortness of breath, etc.. are all very common withdraw symptoms
Visteral is not addicting.
Look up "Benzo withdraw" on youtube, and see if you can relate to any of those people.
I bet a dollar to a donut though thats what it is.
But....you always wanna rule out other problems too.
