Roving symptoms and conditions

I started taking Yasmin this past sunday, so far, so good...reading all these posts worry the crap out of me...i'm only really on this because i have really BAD pms, which people i know including my boyfriend thought it could be PMDD because how "crazy" i'd get, bad cramps and my period sometimes likes to show up almost whenever even when i track it....i'm a moody person already and so far i feel pretty good, pretty stable which is nice, i guess the only complaint is that i'm kinda constipated and i'm exhausted, but i'm unsure if this has anything to do with this pill or not. i travel constantly and eat bad food since i'm away at college so sometimes i have some issues....oh my sex drive is usually pretty fine, i haven't noticed anything there yet, i still think about doing things and want to...so, my question is what should i do? shall i continue to use it and see what happens, or should i stop it or get a different pill?? i go to therapy and i am also making sure that my boyfriend and immediate friends notice if i act a little stranger than usual....
and i was on a different pill back when i was 15 and i don't remember much of it besides i don't think i had any side effects so i've had a little experience with birth control before...

I have been taking 200 mg of lamictal for about 3 years. I am on no other medication. I too have the dry hacking cough that never ever goes away. All day and all night. Dry hacking cough that sometimes leads to gagging. It is terrible. I have had chest xrays, breathing tests and no one can find a reason for the cough. It started about the same time I started this medication and I believe it is the cause. I also experience pain in muscles, it's a roving pain that seems to show up in different places daily, sometimes muscle spasms. My stomach is always nauseated. Very little short term memory, runny nose all the time, constant feeling of having a cold, blurry vision, sensitive to light, little red bumps that appear on my skin, itch, then when they disappear, a scar is left like a cigarette burn. I am reducing the amount of lamictal I take as of this week. I am now only taking 175 mg and will for another week then go down to 150 mg. I am hoping some of these side effects will go away, if not I have to get off of it altogether. It's funny, because I didn't have all these side effects when I first started taking it. Seems the longer I take it the worse it gets. Just can't handle it anymore. wf

Update after stopping Singulair. I stopped taking the drug on March 7th due to sleep disturbances (vivid dreams), depression (constant impending doom and thoughts of death), gastrointestinal disturbance - diarrhea, cramping on lower left side, general IBS symptoms. Following discontinuance, the depression has lessened, not currently to the point where I am the same person as I was (never suffered depression). Sleep has returned to normal, but find days when I become very tired after 5 hours and still go to bed early. This is not every day, some days cannot sleep, others are easy. GI problems became moreso after stopping. Went to the doctor who is doing a colonoscopy next week, I am overdue but the cramping, indigestion and roving abdominal pain bacame worse the first week following cessation and are now subsiding.

I wish I were one of the majority who could take this drug, but unfortunatly am not. Hopefully all negative side effects will be gone in the next few weeks, just hard to believe it did so much to me.
