Got my samples the other day. Last night I used the ZMK sample and loved it. I take adderrall for my add and sometimes (like yeasterday) I mess up and take it later in the day then I should have which results in little sleep. I took then ZMK at about 11 and by midnight I was out like a light. Normally thanks to the addy I would have been up till atleast 3am. Looking forward to trying the Somnidren GH tonight!
