Thanks for replies.
The doctor gave me the option of coming off and trying something else, increasing the dose to 45mg or staying on 30mg for two weeks. That was two days ago. I said I'd stay on 30mg and review in two weeks. My thinking hasn't been great though and I didn't really know which option to choose. I'm pretty horrendous at decision making. But I just felt awful in the days leading up to the appointment and ever since and so I haven't taken it at all these last two nights and don't want to continue with it. I don't know if that was a good move but I didn't like how I was feeling.
