I'm wondering how long it takes to kick in. I've been on for 3 weeks or so at 25mg a day. I have enough for 6 months. I'm not worried about the appetite increase in fact I was hoping for it. I haven't noticed anything yet. For the first couple weeks I did feel lethargic but I feel ok now and it could have just been in my head or there were other contributing factors. My sleep hasn't improved yet either. DG I saw in your nutrabol video that the increase in appetite could occur the first month or so?
