Cosentyx expericences

Hi all, I'm now coming off of methatrexate as it just didn't work for me. I am now going to be starting cosentyx soon. Il be having to inject two pens once a week for 5 weeks them once monthly there after. Could I find out how others have found this, what side affects did you have? How long till your psoriasis cleared? Did you find using the pens easy (I'm a bit scared of this) and anything else you think I should know? Many thanks :)
