What symptoms? Were you started on it slowly and stepped up to 40? And what are your on it for ? Depression, anxiety, OCD? ….

Honestly, every med I’ve tried feels different, so it’s hard to describe. I’ve been on Cymbalta, Zoloft, Abilify, Prozac, Seroquel, and Lamictal. How you know it works is if you notice a decrease in symptoms. That doesn’t necessarily mean that you are symptom free. Over time I know me and several others develop a tolerance and get used to the meds, so we need to switch or increase doses because it becomes less effective. Hope this helps

Symptom wise, I am just moody and having trouble sleeping and staying asleep. I am also somewhat impulsive which is unlike me, and I use it for anxiety
