Just adding my two cents since I have taken anywhere from 50mg to 200mg
For me I didnt notice any real distinct changes. I did have more intense O pains on 150mg but not on 100mg...and I think it was simply because I had two larger follicles instead of 1 average but I did use a trigger shot each time....I will say on 150 mg and up my hot flashes seemed to occur more often, but they werent any more intense. I really didnt have much for side effects at all though...I didnt mind Clomid other than the fact that it didnt work!!! haha
