Thank you so much for that explanation. It is encouraging to hear about the noradrenaline impact. I'm going to ask about XR at my next appointment. My guess is that it's about cost. My first prescription was private and I looked up the prices before getting it - the XR was a lot more expensive. So far I'm doing ok. Euphoria still eludes me but I generally feel more stable, if a bit more anxious. Each increase has knocked me a bit, so I'm not sure what 200-300mg will be like, or how quickly it will be increased, but I'll cross that bridge when I come to it. Thank you again. It's a huge help to be able to ask all these things.
