muscle twitching

I’m having muscle twitching all over my body and it’s been happening for as long as I can remember. I’m currently on 3 meds: Testim (testosterone) Lipitor and lisinopril. What could be causing this problem? The twitching dosent hurt. It’s very irritating. I do drink one cup of coffee a day. I really don’t exercise like I should. My diet is not good either. I’m not always stressed only sometime, for a average person.

Your help is greatly appreciated.

Thank You
