Advice

Okay need some advice on if I should move up or down so I was doing really good on 5 mg with weight loss but I was still hungry so we moved me up to 7.5 and now I have been on it for 2 month and since being on 7.5 not losing anymore and since I have been on 7.5 for two months would it even make a difference to move back down or if it were you would you go up
