Need protein/nutrition, must travel well.

Alright, so here's the situation.

My goals are...

• Work out regularly (lifting weights 3x weekly when home, yoga on other days)
• Use supplements like shakes and quest bars to meet my protein and nutrition goals
• Try to eat within my calorie goals

Not so hard, but some of my circumstances are...

• ADHD, highly medicated, but I also want to include Omega-3, Zinc, Iron, Magnesium, Vitamins C & D without having to remember lots of pills (hence - ADHD - I can barely even remember my ADHD meds, let alone other vitamins)
• I am going to start traveling a LOT for my new job. On average I'll be flying around and staying in hotels 2 weeks out of every month. Whatever I use has to be convenient for flying and consuming in hotels. I'm fine with finding a way to have milk in my hotel to mix with shake stuff.
• While I love being on meds for ADHD and I feel that I'm a much more balanced and successful human while I'm on them, they are messing with my appetite. If I don't plan it out, I could easily go all day without eating more than a few snacks. After realizing this because I feel horrible with low blood sugar, the only thing I can force myself to eat at that point is unhealthy food.

What I've been thinking is...

• Shakeology has options of packets with some protein and also some vitamins. It would travel well and help with my goals, BUT there are many people here saying that it's a ripoff and there are better options. Could those options travel well?
• Quest bars - I loved these in the past. Are these still some of the best protein bang for the buck around? What are some tips to make the most of these in terms of favorite flavors or coupons/deals?
• Are there other products that I should be aware of that may fit my situation?

All thoughts/information is greatly appreciated, with links to resources, reviews, and research even more greatly appreciated!

*Edit - I should also note that I use nuun tabs in my water. Without extra electrolytes, my blood pressure is too low and I pass out. Not sure this is relevant unless there's a supplement that could include this.*
