Hi, I too have taken Zopiclone for a while when I was first diagnosed with anxiety/panic disorder, and have to say that it didn't seem to affect my panic in any negative way. I didn't have any increase whilst using it, and still occasionally use it to sleep ( thats when my gp will let me !! ), as being on venlafaxine find my getting to sleep can be a problem. When I first took it it kind've zoned me out, rather than made me anxious, now I need a heavier dose for it to work. I don't think it should increase your panic in any way, are you anxious about taking it ? Do you think this might be the case ? If you're really worried chat to your doctor again, but I don't know of any link, and I generally well research any medication I have. Good luck, enjoy the sleep ! I think we understimate how much we need it !!
