It definitely sounds like some type of hormone rebound if you didnt notice any of the things youre noticing now until you came off of contraception.
I would first seek advice from a physician. They can run bloodwork to make sure your hormones are correctly in balance. Once they are in balance and the doctor says you are good to go, I would give Alpha-T2 a shot.
Keep us updated on what you hear, but I think getting a hormone panel done would be best. Typically your regular doctor can run this if you have a good doc!
