Has anyone tried...(products)...?

I've just tried a Spark sample the other day and went ahead and ordered some...seemed to give me quite a bit of energy. The day after I was so sluggish and felt horrible. (my norm before changing eating habits to clean eating and gluten free) Hoping I don't feel like that on days I don't drink it...and of coarse my husband blamed me feeling horrible ON the Spark...does anyone have any experience with Advocare Spark?

I've also had C4 recommended to me for a preworkout but was told by someone else it is too strong for me and I should try CLK claiming it was a weaker version of C4. If you have experience with that please let me know your thoughts...

Thanks
