Just tired of feeling tired...help for this fibromyalgia symptom please?

I started Neurontin when I got diagnosed last month. I already was on and continue taking muscle relaxer every night. The Neurontin is great for my pain but if I miss a dose watch out, I am in great pain the next day! I take tramadol for breakthrough pain which is just okay but I still need ibuprophen almost daily. The worst part of this syndrome is the fatigue though! It makes me feel so helpless sometimes and I barely have strength somedays to get showered and dressed and do the things most people take for granted. Today I woke up so strung out feeling and I don't know why? I felt drugged and breathless and really tired and I was soo miserable and could barely move.Could it be because I missed my neurontin dose the night before and when I took it last night it made me feel that way? I was diagnosed with MVP a couple years ago and do get that way sometimes but wonder if that was the cause this morning. I had to take some of my husbands percocet just to get going this morning (he has myofascial pain syndrome) Anyone with personal experience have any tips? I go for a checkup with my Rheumy this week, what can I ask for that would help? Thanks in advance.
