I understand your concern. All prescription drugs have side effects.
I take just one, Lisinopril, for heart.
There are ways to lose weight without those meds. It’s hard to diet in the first couple of months, but soon you become accustomed to eating less. And eating better foods. You make up for higher prices by just eating less. Exercise helps too. Try to walk every day for half an hour at least. In bad weather I got to local supermarket and walk up and down every aisle, get at least 15 minutes.
Of course you could join a gym.
Thanks for the advice.
