I because slightly hypomanic after 11pm and am having fun with music full blast, listening to Tim McGraw if anyone cares. And i took my meds including Lithium and all a sudden my head feels a subtle buzzing feeling. And i got up out of the computer chair and realized how tired i physically feeling. It's like the hypomania collided with the Lithium kicking in. anyone feel funny like that when the dose kicks in? usually i feel it about an hour after taking it. I took it at 12:30am or shortly after and now it's timewarp (timechange) to 3:04am. So little over an hour give or take before it started to kick in i think tonight. When i was on Tegretol i never noticed when it "kicked in". Lithium must be way different. What other meds do you guys feel "kick in"?
