Fairly tired even though I've gotten a good night sleep.

My sleep has improved a TON since starting Effexor. I think I've been getting around 8 hours of sleep for the past week but when I wake up I'm feeling pretty tired which seems a bit weird to me seeing as I am getting more sleep.

The only think I can think of is perhaps I'm dehydrated from the medicine continuing to work overnight. I'm thankfully not excessively sweaty or anything like many people report as a side effect.

Anyone have any suggestions?

I'm already drinking a TON of water each day. I saw someone mention something like drinking water up to 1 hour before bed.
