I've been struggling with a heart that won't calm down for the past month and a half. Called the pharmacy yesterday and found out that my GP made a huge mistake with my medications.

I was suffering from some nasty akathisia because my new antipsychotic was what has me more stable than I've ever felt and I didn't want to lose what I had going for me. So, I was prescribed propranolol. 20mg three times daily. 

Because my blood pressure is normally very low, I decided the extra sluggishness just wasn't worth it. I switched it out for Cogentin which worked better, thankfully. 

But my GP, when I asked, said it was okay to go cold turkey. I was wondering why I was suddenly having panic attacks and feeling out of breath all the time. My resting heart rate this past while averages out to 120. Sitting up, walking, moving in general even at a slow pace shoots it up to 140 or more. I'm fit, I work out often, and my heart rate used to always sit at a comfy 50 at rest.

Thanks to the pharmacist, I found out that withdrawal can last a month or more after tanking my system like I did. I'm finally starting to recover, but I never imagined I could have a reaction like that. The only other times my heart rate has spiked like this, I was mid manic episode. 

Geez, my poor heart is really taking a beating. Bipolar is enough on the system alone. I think I need a new GP...

TL;DR: stopped a decent dose of propranolol cold turkey as per my GP's suggestion due to my low blood pressure. My heart rate has been ridiculously high as a result simulating and encouraging panic attacks.
