Are breaks okay ? Need advice before I start

I'm thinking of starting Reta soon. The thing is, I travel a lot for work and I'm gone for a month + at a time. I researched posts here about travelling with Reta and it's like 50/50 people saying it's fine and others wouldn't risk it. I decided I probably wouldn't risk it, especially because I'm travelling for work and if I get in trouble and get denied entry, I put approximately 20 people in trouble.

My friend who talked to me about Reta said she just finished her first 12 weeks cycle. She is now at her desired weight, so not sure if she's going to do another cycle. I want to do the same, as I can see here that most people can lose around 20 pounds in 12 weeks and that's the amount I want to lose, but I have no guarantee that that's what's gonna happen for me.

My question is, if I do a 12 weeks cycle, stop for 2 months while I travel and start again after, what are the risks, inconvenients, side effects that I can expect on my second cycle ? That is if I'm not able to lose the weight the first time.

Thank you for reading !
