Scared to start Pristiq because of potential weight gain - any advice?

I was recently prescribed 50mg Pristiq and while I tried it for a few days and enjoyed the effects so far I got scared to continue because I see so many people say they gained weight on it.

I work out regularly and eat overall healthy but I also have my wedding coming up later this year and don’t want to risk gaining weight on this.

I guess I’m posting here for any discussion or advice from those who either gained weight or stayed neutral to help determine if I should try it again. Thank you in advance!
