Re: To much medicine that does not go together
I can tell you the levothyroxine is not a "drug" in the sense the other things are. It's a hormone... One that your own thyroid gland would be making if it could. [I suspect your Graves' disease was treated by killing off your thyroid gland so it can no longer make hormone of its own.] Your body needs thyroid hormone... Can't get along without it. It shouldn't be interfering with any of the other meds you're taking.
Glipizide is a diabetic med. If your blood sugar has stabilized (as you indicate), you should talk with your MD about whether you should be taking that or not.
Many healthy people take a daily aspirin in the dose you do in order to keep their hearts in good shape.
The other meds are related to blood pressure control. You probably need those as much as the levothyroxine.
Don't stop taking anything without discussing it with your health professional.
