Feeling extremely depressed after taking Propranolol after two weeks?

One day, I realized I forgot to take it in the morning.  So, I took it later in the day.  Then I had a beer soon after.   I could not believe the emotional rollercoaster, and anger that followed that mistake.   That has been the only time.    I also had some side effects with that manufacturer?    I then traveled to another state, got a diffrent manufacture? or something, and the side effects were far less.     Remember with "slow release", I think there is a coating which causes the slow release.  Do not take with anything that eats that coating off (like beer).  Perhaps soda might do the same.  This is a wonder drug, but I think it increases the frequency of my tics, while making them easier to deal with, so, it's far from perfect.

Have you spoken to your GP? My daughter is on Propranolol for anxiety, but a week after taking it, had concerns they were making her feel worse. What helped her was taking the medication earlier in the day & this alleviated the side effects. If you haven't already, go & see your GP. It may be that this medication isn't right for you or it may be that your GP can offer support as our GP did for my daughter? All the very best.
