JK -- it always takes a bit of time for you both mentally & physically to adapt to a change in diet & program. One thing about committing to working w/ a trainer is to listen to what he says & follow it to a tee. If you second guess his program w/o seeing the larger progression, it may screw up what he's trying to accomplish. I think a good trainer will explain things to you tho - so I would suggest that when something doesnt' make sense or you don't get the reason, ask! But also don't come on here and ask for different opinions when the trainer is the guy driving it. Add input from here to whatever he says, but don't take input w/o the trainer's explanation as well. If he doesn't answer your questions, then I'd either give him shit about it or look for a different trainer. IMO when trainers take you on, they also take on the responsibility of talking to you & answering questions.
RE: the bloat feeling -- ginger root is a good supp for settling your stomach if you do feel like its uncomfortable all the time. But generally the diet you are getting is probably extremely different from what you are used to - so first give it time to adjust and don't scrutinize your body every day - that is as bad as climbing on the scale every hour & freaking out over a 1/2 lb change. Scales suck for tracking progress as they measure bone, lean muscle mass, bodyfat AND water. And speaking as a female w/ the monthly thing, water weight can be an easy 10 lb gain over night. The scale is just a number. In & of itself it is almost worthless as a measurement. I suggest also a re-evaluation of how you "measure" things going forward - again another mental switch that will help you going forward:
1) How do you feel? More energetic? Stronger? Sleep better? Less stressed?
2) How do your clothes fit? These are static measure that you know how each pair of whatever feels on a day to day basis. Looser? Tighter? Tighter / Looser in different places?
3) How you look - this is a catch-22 if you are measuring "how you look" by presence or absence of abs. I don't find looking in the mirror to give me an objective view. Its better to take pix and then look.
4) Bodyfat measure - you said you didnt' want to do this yet. An interesting thing where you know you are already very lean is to look at the relative changes on each pinch point so you aren't just looking at the overall compiled number, but the changes at each of the points - can give you insight into where you tend to hold water or bodyfat or where the muscle mass is increasing. If you look at the changes relative to what your diet has been recently, also gives you an idea of what parts of your diet make you retain water or fat or whatever. But just like the scale, it is just a number and better to look at in terms of relative changes than the actual number. (Also noting at least +/- 2-4% in error).
Like biggt said, the AAS will promote muscle growth & recovery. The EQ will help w/ your appetite, though test may make you retain water a little. But the skinny fat part --- you can bulk or cut on pretty much any drug, because it is driven by your diet & training. If you are eating to build and training to build, hard to get skinnyfat.
