I definitely think that I don't feel any better in myself in terms of symptoms like fatigue and weakness for having NOT taken it, on the days I forget etc. if that makes sense. For example when I had that profound weakness of literally not having my legs hold me, I wasn't taking my propranolol in any disciplined manner everyday. I allowed medication to slide because I was just so poorly after the op. I've invested a small amount in an app to help prompt me to take medications and I've been taking it daily since then and now, unless I was to significantly over do it, while I couldn't stand for very long at all, I can stand to transfer to my wheelchair from bed etc.
