Hi, Paul.
I am one of those who don't like this drug and who have weaned off and quit. But, I have heard from a lot of doctors and patients that only let's say 30% of people have strong side effects. My dad is taking some Beta Blockers and he doesn't have any problems (even though he is tired and sleeps a lot). My grandfather, while he was alive, was taking these drugs for 20+ years and never had any problems. On the other hand, I felt like in hell during taking these drugs.
Also, remember that on majority on forums, it is more likely that people who have some problems with drugs will bother to post and write. If you were feeling fine on drugs, you wouldn't need to go on forums and read other people's opinions since you would like a normal life and you wouldn't care about these forums, more or less.
So, on forums you will usually find customers with bad reviews and some problems with a product, and not people who are happy with a product.
So, a ratio of negative vs positive reviews on forums doesn't reflect a real life ratio perfectly.
So, for start, you may be one of those lucky people who don't have problems with Beta blockers.
Or, if you will have some problems, maybe you will be also among those luckier who have only some mild and tolerable side effects.
About Beta blockers and your question, I don't think that you will have problems if you will take a drug and stop after only 7-10 days. Imo, you need to take a drug for 20-30 or more days and then you can experience some mild withdrawal. But even then, it will be way weaker than a withdrawal after taking a drug for a year, two or ten.
My biggest problem with Bisoprolol and other Beta blockers was inability to breathe.
It was as if my center in the brain which controls breathing was sleeping and I had to manually force myself to breathe majority of time. I had a feeling often as if my lungs forgot to take a breathe and as if signals from a brain to lungs are not coming.
So, I would just sit in my room, or walk, and ask myself: why aren't my lungs breathing normally like before?
When I stopped taking Beta Blockers, my lungs started to receive signals from my brain again and I am breathing normally today.
If you are reading this and you haven't experienced it, it may sound as if I am crazy.
But that is a thing with Beta blockers and other drugs. Only people who have been through the same may understand. These stories may sound totally crazy for normal people.
From other side effects, I was tired, you will have some slight anxiety from time to time, maybe some dizziness.
And in general, my brain and memory felt "foggy", as if you aren't thinking as fast and as clear as your normal self. Also, these drugs affect brain and for example, I had nightmares 1-2 times per week.
While today, off drugs, I have nightmares once in 30-60 days.
I don't know how dangerous is your condition.
It is up to you and your docs to decide what medicine you should take.
About a drug, imo, feel free to cut your dose in quarters and try 0,62Mg for a few days and see whether you feel good or bad and which side effects you feel.
Even though, a problem is that some side effects will start from the day 1, while some will start after a month or two. They don't start right away from the day 1.
So, even if you will feel good after 7 or 10 days on a drug, it doesn't mean that some random side effect won't appear after 30 or 60 days.
But still, if I were you, I would try a drug (in quarters) even for 2-3-4 days.
If you will feel bad right away, at least you will know that you don't want to use it.
If you will feel the same as before, as explained above, maybe you are one of those lucky people who won't have any side effects on this drug.
Good luck
