"i have been taking cymbalta for about 2 months. i started out with the 30mg and now i am taking 120mg 1x day. i take cymbalta for depression, diabetic pain, psoriatic arthritis pain, fibromyalgia, weight loss. but i have noticed about 3 days after starting the 120mg a day my psoriasis flared up very bad. i have not added anything new to my diet. the only different was the increase of the cymbalta. i will keep on taking the medication at that dose. i will just keep on using a lot of creams to help with the psoriasis rash. i must also say i have been losing a lot of weight which is a good thing."
