Need some help!

I’ve got to get this weight off this summer and I’ve tried so many expensive over the counter diet pills that didn’t do anything! Tired of wasting my money. My problem is I NEED energy and none of these pills have helped any with that. I could go to my dr right now for phentermine (adipex) but I don’t want to because I always have weight rebound after getting to my goal. I do try to eat as healthy as I can but the issue is ENERGY I don’t want to do anything much less exercise...anyone that has something that actually works please share.

Thank you!
