I am on a tonne of meds and while stable I am still able to write, play guitar and take photos. At university I get good marks for my creative pieces such as writing and photography. Still, I do find meds do make me slightly less creative. For me PTSD has had more of an impact on my creativity than meds. Now the PTSD is under control (pretty much gone really) I am creative again.

Depression sucks my creativity dry though and hypomania makes me more creative. Idea's flow fast. However, AP's like Zyprexa do badly effect my creativity so I use them sparingly unless in a bad epode like now.
