MRM Driven Pre-Workout Review

Pre-workout supplements are a little tricky for me.  I have a caffeine sensitivity and generally try to avoid it, but sometimes I know my upcoming gym schedule is going to be TOUGH!  Pre-workouts provide extra energy and often contain additional ingredients to aid in muscle recovery or muscle gain, allowing me to get more out of my workout than I would normally.  Some of the pre-workouts I've tried have left me intensely jittery and had other less-than-desirable side effects, so I'm still on the hunt for a pre-workout that works for ME.

I chose MRM Driven over other supplements because it is all-natural AND contains creatine.  Other artificial pre-workouts had me going crazy and getting paranoid, thanks to the synthetic sources of caffeine.  Driven does not give me the same overly tense effects.  I still get an energy boost, and often find it difficult to sleep if I work out in the evening, but I definitely do not suffer from the same intense caffeine side effects of other products.  Occasionally I have itchy skin or mild nausea, but this seems to be linked to the foods I've consumed on those particular days - when I eat healthier during the day, I have fewer side effects. 

The flavor of the mixed berries is okay, but not great, and the powder does not dissolve very well, leaving a dry grittiness to the texture.  I've seen reviews for their other flavor (strawberry kiwi) and it sounds like maybe that's the better flavor choice for this particular supplement.  Overall, though, I found MRM Driven to be drinkable and effective, especially on days when I teach back to back strength and endurance classes and NEED to show up with my A-game and plenty of energy!

Do you take pre-workout?  What's your go-to brand?  Do you have problems with the caffeine content?
