Night 1 &2
I some how deleted my initial post when posting today. I guess I just edited by accident. To recap my initial two nights using both Somnidren GH and ZMK: Night one I had no difficulty falling asleep, but awoke in the middle of the night 2-3 times, but easily passed right back out. Woke up a bit groggy and sleepy in the morning. Day two, I only awoke once during the night and immediately fell back asleep. Woke up feeling well rested and alert. 2nd nights sleep was much better than the first. I've been out of the gym for about 1 week due to a bicep injury, but back in again. I was super sore after my chest/tri workout and also sore after my back workout, but felt the combination of products may have contributed to an increased rate of recovery, but its hard for me to say it definitively did or didn't.
Night 3
Just took the ZMK last night and had another great night of sleep. I didn't awake throughout the night at all and felt refreshed, but a bit groggy for about 40 minutes after waking, but now i'm very alert. Great overall sleep. Will be hitting the gym tomorrow as I have plans this evening.
