@stevetaylor721 Hello and welcome to Connect. My first thought on reading your story is about prescription medications. Have your doctors looked at everything you are taking to see if there are conflicting drugs or a possible allergy to a drug? I was presuming that you may be taking a pain medication since your surgery, so please correct me if that is not the case. I wonder if prescription pain meds can also slow down heart rate. Pharmacists are a great source of information about any drug reaction or interaction, and beyond their normal advice, they can look up more detailed information. Some pain meds are very addicting, and I wonder if your symptoms may be related to that. I don't feel well on pain meds that I was given after surgeries, so I managed without or took minimal amounts and weaned off of them.

Here is some information about Trazodone which is listed as an anti-depressant. https://www.drugs.com/trazodone.html
Here are the overdose symptoms that include vomiting, so this is something to consider. I found more and here are the side effects of Trazodone which does have dangerous interactions with alcohol. It's possible you could be sensitive to this drug.

This is a quote from the link above.

"Report any new or worsening symptoms to your doctor, such as: mood or behavior changes, anxiety, panic attacks, trouble sleeping, or if you feel impulsive, irritable, agitated, hostile, aggressive, restless, hyperactive (mentally or physically), more depressed, or have thoughts about suicide or hurting yourself.

Call your doctor at once if you have:

fast or pounding heartbeats, fluttering in your chest, shortness of breath, and sudden dizziness (like you might pass out);
slow heartbeats;
unusual thoughts or behavior;
easy bruising, unusual bleeding; or
low levels of sodium in the body - headache, confusion, slurred speech, severe weakness, vomiting, loss of coordination, feeling unsteady.

Seek medical attention right away if you have symptoms of serotonin syndrome, such as: agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.

Common trazodone side effects may include:
drowsiness, dizziness, tiredness;
swelling;
weight loss;
blurred vision;
diarrhea, constipation; or
stuffy nose."

This list of side effects mentioned serotonin syndrome. Here is Mayo's information on that with details about the side effects and risks.

Have you consulted a cardiologist? They may be able to figure out why your heart rate has been lowered or if there is another reason for that. I know all of this and thinking about it and not knowing what is wrong is worrisome. It can kind of create a vicious cycle of symptoms that lead to worry, and worry that leads to symptoms. I have been through a full cardiac workup myself because I had chest pains that were caused by stress. They found nothing wrong, so I could take that worry off my plate. My dad was a heart patient, and I always worried that I had inherited that, so I made changes in my life that were heart healthy. The cardiologist confirmed that what I was doing was working because most people have some slight amount of artery blockage at the age I was then (early 50's) and he could find none at all.

I also went through 4 months of panic attacks because I was afraid of surgery and I needed surgery to decompress my spinal cord. I did a lot of things to work through those fears and it worked. I overcame them and I am not paralyzed by fear anymore. That comes with understanding what the problem is, and how to address it. Ask lots of questions. Pay attention to when during the day your symptoms are worse or better, and how does that relate to your medication schedule. Have you had exposure to anyone with Covid? On reading this information I shared, the symptoms you have seem to match the side effects for this drug, so that would be something to ask about if your physician thinks the drug is causing your symptoms. They may not be thinking about that and looking for disease instead.

Do you think your medication may be responsible for your symptoms?
