Bryan, it sounds like weed doesn't do you any good man. If it makes you lazy and sluggish, then you should find a better way to deal with your problems. That isn't cool. Weed does the same thing to me. I tried to perfect every aspect of my life apart from controlling my weed habit, and even still it was fucking with me. There is no way around the fact that weed kills your energy. I have to give it up myself because it's not worth the burnout and side effects of anxiety and depression which I normally do not deal with as a sober individual. Weed numbs my good brain. It's a stupid, deceptive high. I don't actually think that you need to have weed in your life, and it probably makes things worse for you. Just my 2 cents - stop and think is your habit really worth it
It sounds to me like you are self crippling yourself by using drugs all day which zaps your energy, and then asking for a solution to your problem that can only be solved by stopping to use so much drugs. Of course, daily pot smokers are going to offer all sorts of answers because they are in denial about their own drug habits. Green tea sure as hell isn't going to cut it man when you have a heavy drug habit like that - there isn't much of a difference between weed and other shit, it is a drug that can zap your energy and fuck you up if you use it on a regular basis. In fact it has ruined years of my life, and I am quite frankly disgusted by my own dirty drug habit (weed) that I battle with each and every day.
I think if you stopped frequently using drugs, ate healthy, got exercise and stuff, made sure to get sleep, then you would maximize your potential in life.
