This week I have had 2 panic/anxiety attacks - which is quite un common for me. I have had them on and off over the years but 2 in 1 week! I am wondering if it is the Mirtazapine? Sometimes you think great, got one this solved (my sleep) then something else pops up! Like I said, I have had them in the past before. Am i just over thinking about it? The groggyness has also lifted a lot more, which is great. Any info/advisce would be great - I am seeing my CBT therapist on Wednesday so going to discuss with him. Jools
