Do you know which tablet is suitable for good and best sleep?

None: No medication is good for sleep. All are potentially addictive. The safest, best, and most enduring way to get good sleep consistently each night is sleep hygiene - same time each night, no meal within 1 hour of sleep, resolving stress as much as possible, healthy overall, no activities in bed like reading or watching TV - only sleep and sex, and limiting alcohol, caffeine, and excess sugars.
