I'm also on Toprol XL (motropol) and I found that right after I started taking it I was tired and dizzy and short of breath. I also have copd/asthma and this drug doesn't help those those issues.
There is a recall on that Valsartin, I suggest you get off that drug and call your doctor for replacement.
When my husband had his heart attack he was only on Plavix for a year, if you need a blood thinner there are better ones out there. I do think it's all the meds you are on causing your problems.

I am on some of those meds and they do make you tired by noon I am exhausted I am 56 and haven't worked in 2 years had a heart attack last June didn't realise my arteries were blocked till the heart attack but I did have more energy before the meds even with the blockages.

I think it's the medicine, I am on most of the same ones you are on. I too am very tired, and very winded and still get chest pains. I too have clear arteries, I wonder if you too have SCAD, where you have tears in your arteries.?

Yes I get the same symptoms and feel drained with low mood

I have this fatigue its dificult to handel but I must follow a good diet apparently my bloodsuger goes down
