Hi LMA10
I can’t relate to codeine making my anxiety worse while i was on it but it definitely stopped “fixing” all my problems, like anxiety and depression. I can only imagine how bad your anxiety is now after 5 days no codeine too.
I mentioned in an earlier post that i was prescribed propranolol and it’s been helpful for exactly what you’re describing – overwhelming fear and anxiety, shaking, palpitations, shortness of breath etc. It’s not perfect and won’t magic you back to health but it’s put a limit on how much my body can go through (no freezing or panic attacks since i started it).
Please be kind to yourself, you’re doing so well. Keep posting here. I found 5 days the hardest. They say 3 days but i gave in at 5 days twice. Try and get as much rest as you can and stay hydrated.
