If you took the 100 mg dose, you’d still have 50 mg in your system after 8.5 hours. Now today is Sunday and in Monday morning you have less than 25% drug in your system.It's good to discuss rather than quit.Please avoid poor/bad rating.Positive feedback and bonus are highly appreciated if you satisfied with our conversation.Thanks.
