Coming off phentermine after 9 months

Hi everyone. I am down to my last dose after 9 months on phentermine (37.5 mg). My weight loss was slow but steady, and I lost weight at every check up, so my doctor let me stay on it until now. I’m down about 45 pounds and met my goal, although it was conservative and I am not where I want to be. My BMI is 27 so I’m still considered overweight which effects my health insurance premium. I am very concerned about the food noise coming back, and losing the focus that the phentermine gave me. I never got a huge jolt of energy that some get, I just felt normal, not exhausted or unmotivated. Has anyone found a supplement that helped during the transition? I was looking into a daily B12 maybe. I do already take plenty of vitamin D as I’m extremely deficient. But I’m looking for any other ideas to give me a boost, as long as they are healthy options. I’d prefer a gummy or patch since I don’t always handle pills well. Thank you!
