I would like to know how long I wait until taking my usual dose of 88mcg and what to do about the blood test I will be getting in 4 more days. I am also on lithium carbonate 600 mg a day and 75 mg of seroquel at night, The pill somehow got in my pill case with the two other meds when I filled it. This has never happened before. I looked up overdose and it states that I could have rapid heart beat, however this has not happened to me, I do not feel excited or nervous or anything of that sort. I always take my meds right and just need to know when to take the next dose, I worry I could have mania again as before when summer was real hot, but have not had this this yr and am staying in where it is cool to help prevent it. Thank you very much for your help in this.
