Sorry to hear you're having tough times, OP!
It sounds like the new medication is effective and you know what that means: increase detox.
At times such as these, I've found it helpful to review the site I'm linking below and choose a few detox methods to add:www.tiredoflyme.com/detox-methods.html
And, as long as you work towards keeping yourself healthy, you shouldn't be dealing with this nonsense for the rest of your life. It, too, shall pass (with effective detoxing ;).
