Salesforce error: Too many code statements 200001 - apex-code

Question

I have created an opportunity trigger to send out an email to two separate email address field whenever the stage is Closed Won depending on the Campaign Type. It works perfectly fine but recently when I tried updating a list of 200 opportunity records it gave me an error saying "Too many code statements 200001".
My code is as follows:
trigger SendEmail on Opportunity (after update)
{
Set<Id> accountSet = new Set<Id>();
Set<Id> marketSet = new Set<Id>();
for (Opportunity o : Trigger.new) {
accountSet.add(o.Accountid);
marketSet.add(o.Campaignid);
}
Map<Id, Account> accountMap = new Map<Id, Account>([SELECT Name, Phone, PersonMobilePhone, PersonEmail from Account where id in :accountSet] );
map<Id, Campaign> marketMap = new Map<Id, Campaign>([SELECT Name, Parent_Market__c from Campaign where id in :marketSet]);
for (Opportunity o : Trigger.new) {
if(o.Campaign_Type__c != Null && o.StageName != Null){
for (Integer i = 0; i < Trigger.old.size(); i++) {
Opportunity old = Trigger.old[i];
Opportunity nw = Trigger.new[i];
Account theAccount = accountMap.get(o.AccountId);
Campaign Market = marketMap.get(o.CampaignId);
String userName = UserInfo.getUserName();
Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
List<String> toAddresses = new List<String>();
List<String> ccAddresses = new List<String>();
ccAddresses.add('test#test.com');
mail.setToAddresses(toAddresses);
mail.setCcAddresses(ccAddresses);
mail.setSenderDisplayName('Campaign Information');
mail.setSubject(+ theAccount.Name + ' is Closed Won');
mail.setReplyTo('noreply#salesforce.com');
//Body of the Email
mail.setHtmlBody(
'<font face="Times" size="3">'+
'<table width="100%">'+
'<tr width="0%">'+
'<td rowspan="0">'+
'</td>'+
'<td>'+
'<h2>Account is closed won notification</h2>'+
'</td>'+
'</tr>'+
'</table>'+
'<br/>'+
'<b>Stage:</b> ' + o.StageName + '<br/>' + '<br/>' +
'<b>Opportunity Number:</b> ' + o.Name + '<br/>' +
'<b>Amount Paid:</b> $' + o.Amount + '<br/>' + '<br/>' +
'<b>Account Name:</b> ' + theAccount.Name + '<br/>' +
'<b>Phone:</b> ' + theAccount.Phone + '<br/>' +
'<b>Mobile:</b> ' + theAccount.PersonMobilePhone + '<br/>'+
'<b>Email:</b> ' + theAccount.PersonEmail + '<br/>'+
);
// Send Email if it isCampaign1 and Closed Won
if((nw.StageName !=old.StageName) || (nw.Campaign_Type__c !=old.Campaign_Type__c)){
if(o.Campaign_Type__c.equals('Campaign1')){
if(o.StageName.equals('Closed Won') ){
toAddresses.add(o.Email__c);
try {
Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });
}
catch(Exception ex) { }
}
}
}
// Send Email if it is Campaign2 and Closed Won
if((nw.StageName !=old.StageName) || (nw.Campaign_Type__c !=old.Campaign_Type__c)){
if(o.Campaign_Type__c.equals('Campaign2')){
if(o.StageName.equals('Closed Won')){
toAddresses.add(o.Email2__c);
toAddresses.add(o.Email1__c);
try {
Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });
}
catch(Exception ex) { }
}
}
}
}
}
}
}
Any help will be appreciated.
Thanks

Why you sand for each opportunity Trigger.new.size() emails?
your code degree is n*n.
Change
for (Opportunity o : Trigger.new) {
if(o.Campaign_Type__c != Null && o.StageName != Null){
for (Integer i = 0; i < Trigger.old.size(); i++) {
Opportunity old = Trigger.old[i];
Opportunity nw = Trigger.new[i];
To something like
for (Opportunity o : Trigger.new) {
if(o.Campaign_Type__c != Null && o.StageName != Null){
Opportunity old = Trigger.old.get(o.Id);
Opportunity nw = o;
if(((nw.StageName !=old.StageName) || (nw.Campaign_Type__c !=old.Campaign_Type__c)) && (nw.StageName.equals('Closed Won')&&((nw.Campaign_Type__c.equals('Campaign1')||(nw.Campaign_Type__c.equals('Campaign2')){
