Why can't i sleep w/o meds? my anxiety seems to be under control mostly & depression, good sleep hygiene, can't sleep on my own. i've tried everything.

Hard to say: Sleep hygiene is important as is exercise early in the day. Perhaps depression or anxiety symptoms are not totally resolved. Excess caffeine or other stimulants like nicotine can be involved. Drug use such as alcohol at be involved. For an answer specific to you work with your healthcare team closely. Meditation and relaxation exercises can be important too.

Magnesium supplement: After using sleep hygiene (find that on the internet) another thing to try is magnesium supplementation. That can help with anxiety/restless legs/and sleep. Try 400-500mg before bed. There are many forms and all are good except for magnesium oxide because it's poorly absorbed. Anyone with normal kidney function can try this.
