Side effects of clomid: at higher doses (100mg/day or more) after 10-15 days you will start to get vision artifacts, streaking or blurring of motion especially in low light conditions. It is odd and trippy, but it didn't bother me. A worse side effect that seems to bother many people is clomid makes you moody as hell. It makes some people very depressed, others just cry over little things. It doesn't have this effect on me so I use it. But about 50% of the people I have talked to avoid clomid because they dislike this side effect.
