Suppliment regimen/exercise advice please

[BustedS13]

I've lost a substantial amount of weight over the past two years through diet and exercise. Last month I decided to go a step further and joined a gym, and have been putting in an hour of cardio five days a week on average, but have been neglecting anaerobic exercise during that time. I'm now about to begin half hour cardio sessions coupled with weight lifting three days a week, and squeeze in an hour of straight cardio one or two more times per week. ANYWAY,

I've always tried to take vitamins on a regular basis but tend to forget/neglect them. I've been good for the past week, (and this is where I'd like your advice) taking: -walgreens men's daily multivitamin -3g fish oil -5000iu vitamin d3 -Eca stack (25mg ephedrine, 200mg caffeine, 3x/day; omitting aspirin because fish oil makes it redundant/i don't want to die) -6g creatine

I've gained significant weight over the week, which I believe is water retention due to the creatine. I'm pretty weak, and thinking I jumped the gun with it anyway, so I'm going to stop taking creatine for at least a few weeks to see if my weight drops back to where I think it should be. So, does this sound like a decent regimen? I have normal blood pressure, my cholesterol is fine, no history of heart disease or any other issues like that in my family. I know there's a lot of body conscious people on this forum, which is why I'm asking here, obviously. I know some people are against the Eca stack, but I like the energy and appetite suppression and have had success with it before. Opinions please! Thanks.
