Aha, well this may explain the enormous (and when I say enormous, I really mean it) amounts of anxiety I’ve been feeling lately. The increase in Seroquel may well be the culprit! I’ve been thrashing around in my sleep even, as my friend “Blahpolar” amazingly surmised. Seroquel increases epinephrine (adrenalin) and norepinephrine (noradrenaline.) Which are involved in the fight or flight response, also in alleviating depression, as well as in causing anxiety, aha!

I have been having awful anxiety and now my muscles are starting to get very stiff, another adverse effect of Seroquel.

Ah yes, as it saves you, it also kills you. Have to be vigilant about the beginning of these adverse effects and cut them off at the pass, Kimosabe.

Well at least it’s good to know what is likely happening with me. Thank you Blahpolar for your ingenious understanding of my symptoms.
