How did you know when to increase dose or stay?

I've been taking 5 for the last few weeks and am scheduled to bump up to 7.5 next week. But I'm not sure if it makes sense to do that. I still have pretty solid hunger suppression, even day 6.

I still want to be able to eat something so I don't get light headed and sluggish.

I think I'll probably try the higher dose and see how it goes. Just curious how you decided when to stick to a certain dose as I've seen some people going all the way up to 15 and some who are staying at 2.5,
