my roommate is currently taking 300mg of lamictal and 200mg of geodon. she is also on klonopins (not sure of the mg), oxcarbazepine (not sure of the mg) and some type of antibiotic. She has been diagnosed with bi-polar, PTSD and anxiety. some of her doses seem high to me and I m concerned (as is she) of interactions between these drugs and some of the things she has been experiencing with her body. she has complained about feeling like she is shaking on the inside (yet she isn t on the outside), feeling dizzy, upset stomach, spacing out, difficulty thinking or remembering, and some times lack of sleep. could this be due to her medication or due to her condition or both? i have talked to her about getting a second opinion about what she is taking, should she do that?
