Moving from 2.5 to 5

Hi

I'm at the end of week 2 and so far have lost 4.6lbs, am eating so much healthier, am far less bloated and am sleeping really well. I've had minimal side effects - a metallic taste in my mouth and a headache the second day after I jab. I have appetite suppression and reduced food noise but it's starting to wear off towards the end of the week

My goal is to lose 2lbs a week, I want to keep it fairly slow and steady as I'm quite active and dont want to be too fatigued.

I'm currently deciding whether to move up to 5, I've heard that a lot of people struggle with the jump. I'd love to know about everyone's experiences, anything to watch out for, how long the harder side effects lasted for?
