I guess the more appropriate question would be, for those who've used this drug, how long did it take your bodies to get use to it? It is 9/4 I have been on this only since 9/2 and it makes me very dizzy, confused and tired. I am suppose to take it twice daily (morning & night) but right now I am taking both doses at night. If I take one in the morning I can't drive, work or care for my son. I am hoping that once my body gets use to the medicine, it won't be such a shock to the system and I can take it twice daily as directed so that it will be more effective. I was just wondering when to expect this change to take place; when most people feel that their bodies were use to the medicine. Also, please share if you've experienced the same side effects and whether they completely went away or not. Thanks in advance!
