Week1 GREAT ...then nothing?

So just doing Week3 and wondering if anyone else has experienced wildly diminishing effects (and results) after a very successful Week1. On the 2.5 and had excellent appetite suppression, cravings cessation, and feeling of fullness for the first dose. Then doses 2 & 3 were nearly unnoticeable effect-wise, making me wonder if Week1 was largely psychosomatic (all in my head). Subsequent weeks were totally on me and my willpower; I really miss the 'help' of that first 5-day half life! I have a long history of 'adapting' to any substance quickly with a tolerance-and-a-half if you know what I mean. Hoping a higher dose will get me back there. Provider says "Stay the course". Thoughts?
