Sativa gummies (50mg) made me fell energetic for a while, too, but they also made me feel kind of high, but not comfortably high.
I only used them for several days when my regular pain med was delayed (because CVS is the drug gestapo). And I was never into MJ, so I'm probably a total lightweight compared to people who use (or used) it fairly regularly.
That said, I have a major battle with energy. Chronic pain drains it from me mentally and physically. My solution is 5-hour energy shots. The top 3 ingredients in 5-Hrs are vitamin B12, B6, and taurine, and it's in liquid form, which is the best way to take B vitamins because your body only absorbs a small percentage of it when you take it in pill form.
I drink a whole shot at about 8 a.m. to wash down my morning Rx meds, then a 1/2 shot to wash down my 2pm meds. The morning shot keeps me energized and productive until at least noon - so, for at least 4 hours, I have plenty of energy, I'm mentally sharp, and I'm in a pretty chipper mood even when my pain is too much for my medication to manage.
