Losing hope

I’ve been taking metformin for about a month and a half and I’m so tired of the side effects. I feel like it’s not working for me and I’m losing hope. I’ve tried multiple diets to help lose weight, that’s not working, the pill itself isn’t making me lose weight, and I haven’t had a period yet. I go see my doctor next month to check hormones and stuff but until then what can I do? What diet worked best for you to get results? What kind of workouts did you do? I don’t want to give up on it if it’s working on the inside and I’m just not noticing it.
