I started 300mg lithium 1wk ago. I felt amazing. It was like the flip was switched back in in my brain. I had motivation, energy, I had happy thoughts, enjoying life etc. Well I missed a dose of Effexor 2days ago and did not take lithium last night because I initially thought me feeling sick was from the lithium (it was the Effexor) anyways today I am dragging, I am so so tired, my mood is blah, could just sleep and sleep. So question is, could this be from the screw up in pills or is it just that last wk was just a honey moon phase. Will I get to feeling good again?
