What is your take on caffeine to help with the fatigue?

So I've had MS for 2 years now, diagnosed for 1 1/2 years. If I ignore the "small" stuff, the hardest part for me is the constant fatigue. I've tried improving my diet (cutting out my daily energy drink and eating way less junk food, think less chips more fruit), getting more sleep, sleeping less (in case I was over sleeping), eating more protein (my dietitian recommended it), and taking a daily vitamin B Minus pill in addition to all my other meds, some of which have changed recently. However even with all these changes I'm still so tired all the time. My boyfriend has recommended trying meditation to help calm my mind and help focus to see if that helps, however the few times I've done it successfully I've been even more exhausted after (I did it on my lunch breaks). Truthfully, I miss my daily energy drinks. I know they aren't good for you but they helped and I wasn't so tired I wanted to cry. So now I need y'all's advice. I don't know what to do at this point. He's been trying to help me stop drinking the energy drinks longer than I've had MS but I'm so damn tired all the time and it only feels like it's getting worse not better. I don't know what to do anymore. I have an appointment with my neuro in a few weeks and I plan to ask him but I was wondering if anyone had any advice in the meantime. Also I don't know if it helps but I'm located in the US I and I have to get up at 6:30am for work M-F and every other Saturday.
