Palo Alto Labs has just come out with a product called Reset AD that's supposed to help recover from stimulant addiction. You may want to go check it out, as it says it will curb that sluggish feeling in the morning. And try to cut back on the caffeine a bit, too, slowly. You're pretty classic symptoms of caffeine addiction. Message me if you have any questions.
I just got a bottle to give it a shot but I'm not sure if it's working or not yet, as my schedule is off the hook and I'm not sleeping enough period. But it was only 15 dollars for a month's worth, so it may be worth a shot. Shouldn't interfere with any other supplements unless you take GABA.
