Did anyone else have these initial reactions to Wellbutrin?

So I told you all I’d give you an update. This is my first day taking Wellbutrin. I’m supposed to start off at 75mg and eventually work my way up to 150mg. You’re supposed to take it in the morning because apparently it can keep people up at night.
Right now I’m feeling exactly the opposite and I took it about 4 hours ago. I feel really lightheaded. Like my head is a balloon. I feel really detached from my surroundings and rather unemotional (which, I have to say is a nice break). I sort of feel like I’m in a fishbowl.
I know it’s only my first day and I’m sure the side effects will all change and I will acclimate to the drug. I was just curious if anyone else had similar initial reactions.
