Lamictal and insomnia

I have ADHD and persistent depressive disorder. I just started both Lamictal 25 mg and Adderall IR 10 mg, both taken in the morning, on Friday. I also have insomnia, I fall asleep easily but wake up after a few hours so I use a vibrating watch set to midnight and take temezapam for sleep, which used to work for 6 hours. Since starting the meds the temezapam seems to have completely stopped working and I'm drowsy but don't feel like I'm sleeping and I'm having vivid dreams. I have a busy brain and just can't shut it down. Also peeing a lot and my night sweats due to menopause have returned, which doesn't help my sleep. I use HRT and there is an interaction with the estradiol so I wait 4 hrs to take that per Dr recommendation. Could the Lamictal be causing the insomnia? I don't find the Adderall very activating, just helps my God awful fatigue. Interested in your thoughts, Reddit friends.
