So I have been on 30mg cymbalta for 7-8 years now for an acute anxiety disorder. I am trying to figure out why I have put 25 lbs over that time with no change in life style. I'm 5'5" and 168. I often feel foggy brained, need a nap daily, I have a deviated septum and snore nightly but a sleep study about 8 years ago said nothing? I get unmotivated but try to ignore and push on. Not a big eater but often when I do even after just a coffee and creamer in the am I get a dull headache and can last all day. Gives a feeling of heaviness? I just feel alil off and tired and not sure what to do! Been this was for some time... Just ignored it!
