25 to 50 - hoping it was a right decision

I almost completed 4 weeks on 25mg. The last 3-4 days were GREAT! Felt completely normal. So lets say Fri to Tues was amazing. Since the upping was due, in between on Sunday, I changed to 50mg. Today is Wed and I woke up with morning anxiety and nausea again..

Assuming its normal ? Or did i make a blunder moving 25 to 50.
