Can’t sleep on Effexor 😴

Anyone else find Effexor too activating? When I was on 37.5mg, I had no issues taking it at 6pm and being able to sleep through the night. Now at 75mg, I wake up several times throughout the night, and feel as if I’m caffeinated. Wondering if this is a potential side effect and if anyone else can relate or has any tips to help this?
