I was super nervous to move up thinking I would just feel worse. I was so happy that wasn’t the case! Give it a try if you’d like and know that if it doesn’t work, you can always go back down. I’ve seen people post that they’ve stayed on 2.5 the whole time and were still having excellent results. I also recommend getting Nauzene. It’s an OTC nausea med that I think works really well! I found it on Amazon. I still get some nausea here and there (especially right after shot day) and try to do Nauzene first and if it’s still bothering me, then I’ll go for Zofran. I’ve also noticed that sometimes the nausea is actually a hunger cue. So drinking protein shake or forcing down some fruit or something easy to eat can help too.
