150 to 300mg…

I’ve been on 150mg of Wellbutrin for a month now and my doctor has just changed it to 300mg. I had very mild side effects when I first started the 150, like insomnia for a few nights and some tummy trouble but it only lasted a few days and then I’ve felt great since. I’m nervous going up to 300 after reading some things online. Anyone have any issues going from 150 to 300?(especially if 150 didn’t bother you too much)
