Hammer products seem to work well for lots of folks, for others (like me), not so much. I haven't used their products for hiking/backpacking, but I have trained and competed in endurance events (open ocean long distance paddling) while using their products and found that they didn't agree with my stomach. It got to the point where I preferred to not drink anything rather than continuing to drink my prepared drink mixes. This didn't do my energy levels any favors but my stomach sure felt better.
Anyway, the point I'm trying to make is that there are lots of options out there for similar style products from other manufacturers. I recommend you try out one or two, on a very limited basis first to see what works for you and what doesn't. Once you've found something that you think you like and respond well to, you can then try building up your usage of it and relying on it more and more to provide your needed energy for a given activity.
I've found that Succeed products work well for me. I supplement their drink mixes with Carbo-pro powder and/or eletrolyte and sportlegs tablets when needed. I find these mixes to be much lighter on my stomach and much more mild in flavor.
I don't have any affiliation with any of these companies; just wanted to share my experiences as I've been down this road and tried a bunch of different similarly-marketed products.
